Yajurveda (Samskrit: यजुर्वेदः)

Talk on Yajurveda

परिचयः ॥ Introduction

Also, known as Adhvaryuveda. Has 18 Parishishtas. In the Bṛhadāraṇyaka Upaniṣad, vi. 4, 33, there is a reference to the śuklāni Yajūṃṣi, ‘white or pure Yajus,’ as promulgated by Vājasaneya Yājñavalkya, whence the Vājasaneyi Saṃhītā is popularly known as the ‘White Yajurveda.’

Puranic Encyclopedia

The Caturvedas are:--ṛgveda, yajurveda sāmaveda and Atharvaveda. viṣṇu purāṇa, Part 3, Chapter 5, mentions that vaiśampāyana, the disciple of vedavyāsa, divided yajurveda into twentyseven branches and taught them to his disciples. Among those disciples there was yājñavalkya, the son of Brahmarāta. It was vyāsa who divided the Vedas into four parts. After dīviding them, the sage vyāsa taught ṛgveda to paila, yajurveda to vaiśampāyana, sāmaveda to jaimini and Atharvaveda to sumantu.

The rules for japa, homa etc. of yajurveda were taught to vyāsa by Agnideva. If all the rules of yajurveda are correctly observed, all desires will be fulfilled. There are special rules for the observance of homa for the fulfilment of particular desires.

-जुः) The Yajur or Yajush, one of the four Ve4das; it is divided into two principal portions, the white and black, or Va4jasane4yi and Taittiri4ya, the former of which is attributed to the saint YA4JNAWALKYA, to whom it was revealed by the sun, in the form of a horse; and the latter to TAITTIRI, to whom it was communicated by YA4SKA, the first pupil of its original author, the sage VAIS4AMPA4YANA: according to the Pura4n4as the Taittiri4ya portion was named from Tittiri a partridge; the disciples of VAIS4AMPA4YANA being changed into those birds, to pick up the texts of the Ve4da as they were disgorged in a tangible shape by YA4JNAWALKYA, at the command of VAIS4AMPA4YANA: both portions of this Ve4da are very full on the subject of religious rites, and the prayers peculiar to it, are chiefly in measured and poetical prose.

Yajus : nt. (sg. or pl.): Sacrificial prose formula from the Yajurveda; when used in plural it stands also for the Yajurveda; when in plural, it mostly occurs with ṛcs and sāmans.

Gift of Āditya to Yājñavalkya: The sage Yājñavalkya told king Janaka that while he was practising the prescribed rite, (although) he was despised (? avamatena), he propitiated the god Sun with severe austerity; he then received from Āditya the yajuses (yathārṣeṇeha vidhinā caratāvamatena ha/mayādityād avāptāni yajūṁṣi mithilādhipa//mahatā tapasā devas tapiṣṭhaḥ sevito mayā) 12. 306. 2-3; when the pleased god Sūrya offered a boon to Yājñavalkya, the latter requested the god to grant him the yajuses which had not been used before (? yajūṁṣi nopayuktāni kṣipram icchāmi veditum) 12. 306. 4-5; the god agreed to Yājñavalkya's request; Sarasvatī then in the form of speech entered Yājñavalkya's mouth 12. 306. 6-7; the God said that as a result of that, the whole of Veda (i. e. the Yajurveda) together with its latter half and the khila would be established in him (Yājñavalkya) (pratiṣṭhāsyati te vedaḥ sottaraḥ sakhilo dvijā) 12. 306. 10 (Nī. on Bom. Ed. 12. 318. 10: khilaṁ paraśākhīyaṁ svaśākhyāyām apekṣāvaśāt paṭhyate tat khilam ity ucyate/…sakhilam tatsahitam/ sottaraṁ sopaniṣatkam/); Yājñavalkya received fifteen yajuses from Arka (Sūrya) (daśa pañca ca prāptāni yajūṁṣy arkān mayānagha) 12. 306. 21; Sūrya gave the yajuses (to Yājñavalkya) in the east (atra (i. e. in the east) dattāni sūryeṇa yajūṁṣi) 5. 106. 11 (Nī on Bom. Ed. 5. 108. 11: yājñavalkyāyeti śeṣaḥ).

All about Hinduism - Swami Sivananda

The Veda is divided into four great books: the Rig-Veda, the Yajur-Veda, the Sama-Veda and the Atharva-Veda. The Yajur-Veda is again divided into two parts, the Sukla and the Krishna. The Krishna or the Taittiriya is the older book and the Sukla or the Vajasaneya is a later revelation to sage Yajnavalkya from the resplendent Sun-God.

The Rig-Veda is divided into twenty-one sections, the Yajur-Veda into one hundred and nine sections, the Sama-Veda into one thousand sections and the Atharva-Veda into fifty sections. In all, the whole Veda is thus divided into one thousand one hundred and eighty recensions.

The Yajur-Veda Samhita is mostly in prose and is meant to be used by the Adhvaryu, the Yajur- Vedic priest, for superfluous explanations of the rites in sacrifices, supplementing the Rig-Vedic Mantras.

The Satapatha Brahmana belongs to the Sukla Yajur-Veda. The Krishna-Yajur-Veda has the Taittiriya and the Maitrayana Brahmanas. Each of the Brahmanas has got an Aranyaka.

There are as many Upanishads to each Veda as there are Sakhas, branches or recensions, i.e., 21, 109, 1000 and 50 respectively to the four Vedas, the Rig-Veda, the Yajur-Veda, the Sama-Veda and the Atharva-Veda.

Among the Kalpa Sutras, The Katyayana and Paraskara belong to the Sukla Yajur-Veda. The Apastamba, Hiranyakesi, Bodhayana, Bharadvaja, Manava, Vaikhanasa and the Kathaka belong to the Krishna Yajur-Veda.

Chapter 1

Yajurveda is the collection of yajus used by the Adhvaryus. The term yajus derived from yaj + usi is used in the sense of Yajniya prarthana or mantra. The mantras in Gadya (prose) uttered by the Adhvaryu while performing Yajna-vidhis are known as Yajus. The mantras different from Rk and Sama are designated as Yajus.

The term Yajuh is variegatedly explained as follows:

अनियताक्षरावसानो यजुः । The one in which the number of syllables is not designated or fixed.

गद्यात्मको यजुः । and शेषे यजुः । suggest that the prosaic mantras apart from the rks and samans are termed as yajus.

शाखाः ॥ Recensions

The Yajurveda text includes Shukla Yajurveda of which about 16 recensions are known, while the Krishna Yajurveda may have had as many as 86 recensions. Only two recensions of the Shukla Yajurveda have survived, Madhyandina and Kanva, and others are known by name only because they are mentioned in other texts. These two recensions are nearly the same, except for few differences. In contrast to Shukla Yajurveda, the four surviving recensions of Krishna Yajurveda are very different versions.

The Krshna Yajurveda has survived in four recensions, while two recensions of Shukla Yajurveda have survived into the modern times.

Baldev Upadhyay (1955), Vaidik Sahitya, Kashi

There are two Sampradayas of the Vedas viz. Brahma Sampradaya and Aditya Sampradaya.

According to the Shatapatha Brahmana, Shukla Yajurveda narrated by Yajnavalkya represents the Aditya Sampradaya.

आदित्यानीमानि शुक्लानि यजूंषि वाजसनेयेन याज्ञवल्क्येनाख्यायन्ते १४.९.५.३३

Consequently, the Krshna Yajurveda represents the Brahma Sampradaya.

The differentiation of the Yajurveda into Krshna and Shukla is to do with their content.

The Shukla Yajurveda has a collection of only mantras essential for performing rituals like darshapurnamasa, etc. While the Krshna Yajurveda also includes the relevant brahmana portions therein. The combination of mantras and brahmanas defines the nature of Krshna Yajurveda and the unalloyed collection of mantras alone defines the nature of the Shukla Yajurveda.

Shukla Yajurveda

The samhita in the Shukla Yajurveda is called the Vajasaneyi Samhita. The name Vajasaneyi is derived from Vajasaneya, patronymic of sage Yajnavalkya, and the founder of the Vajasaneyi branch. There are two (nearly identical) surviving recensions of the Vajasaneyi Samhita (VS): Vajasaneyi Madhyandina and Vajasaneyi Kanva. The lost recensions of White Yajurveda, mentioned in other texts of ancient India, include Jabala, Baudhya, Sapeyi, Tapaniya, Kapola, Paundravatsa, Avati, Paramavatika, Parasara, Vaineya, Vaidheya, Katyayana and Vaijayavapa.

Krishna Yajurveda

A total of eighty six recensions are mentioned to exist in Vayu Purana, however vast majority of them are believed to be lost. The Katha school is referred to as a sub-school of Carakas (wanderers) in some ancient texts of India, because they did their scholarship as they wandered from place to place.

The Maitrayani saṃhita is the oldest Yajurveda Samhita that has survived, and it differs largely in content from the Taittiriyas, as well as in some different arrangement of chapters, but is much more detailed.

The Kāṭhaka saṃhitā or the Caraka-Kaṭha saṃhitā, according to tradition was compiled by Katha, a disciple of Vaisampayana. Like the Maitrayani Samhita, it offers much more detailed discussion of some rituals than the younger Taittiriya samhita that frequently summarizes such accounts. The Kapiṣṭhala saṃhitā or the Kapiṣṭhala-Kaṭha saṃhitā, named after the sage Kapisthala is extant only in some large fragments and edited without accent marks. This text is practically a variant of the Kāṭhaka saṃhitā.

Baldev Upadhyay (1955), Vaidik Sahitya, Kashi

The Taittiriya shakha is the prime shakha of the Krshna Yajurveda. There is a famous narrative about the same. It is said that fearing the curse of Guru Vaishampayana, Yajnavalkya vomitted the Yajus studied by him and as per the instructions of the Guru, other shishyas took the form of tittiris (birds) and consumed the vomitted yajus. And by the grace of Bhagavan Surya, Yajnavalkya obtained the Shukla Yajurveda.

Organization

Each regional edition (recension) of Yajurveda had Samhita, Brahmana, Aranyakas, Upanishads as part of the text, with Shrautasutras, Grhyasutras and Pratishakhya attached to the text. In Shukla Yajurveda, the text organization is same for both Madhayndina and Kanva shakhas.

In Krishna Yajurveda, each of the recensions has or had their Brahmana text mixed into the Samhita text, thus creating a motley of the prose and verses, and making it unclear, disorganized.

Contents

Samhitas

Structure of the mantras

The various ritual mantras in the Yajurveda Samhitas are typically set in a meter, and call on Vedic deities such as the Savita (Sun), Indra, Agni, Prajapati, Rudra and others. The Taittiriya Samhita in Book 4, for example, includes the following verses for the Agnicayana ritual recitation (abridged)

Brahmanas

Baldev Upadhyay (1955), Vaidik Sahitya, Kashi

There are two major brahmana texts of the yajurveda that are available viz.

1. Shatapatha Brahmana belonging to the Shukla Yajurveda.
2. Taittiriya Brahmana belonging to the Krshna Yajurveda.

The Shatapatha brahmana is available in both the Madhyandina and Kanva shakhas of the Shukla Yajurveda. Though their subject-matter is the same, there are slight variations in the order of description of Yajnas and the number of adhyayas.

The Madhyandina Shatapatha brahmana consists of 14 Kandas, 100 adhyayas, 68 Prapathakas, 438 brahmanas and 7624 kandikas. While the Kanva shatapatha brahmana is organised into 17 kandas, 104 adhyayas, 435 brahmanas and 6806 kandikas.

Both the Shatapatha as well as the Taittiriya brahmana are endowed with svaras suggesting their antiquity. And the pronunciation rules of the Shatapatha brahmana follow that of the Vajasaneyi Samhita (Shukla Yajurveda), the Madhyandina Samhita to be more specific which is natural given the brahmana belongs to the Madhyandina shakha of the Shukla Yajurveda.

The Taittiriya brahmana is the only available brahmana of the Krshna Yajurveda shakha. It consists of 3 Kandas (ashtakas), 28 adhyayas (prapathakas) that are further divided into anuvakas. It enlists the mantras pertinent to every ritual of which many are reiterated from the Rgveda. Interestingly, the brahmana also answers many questions posed in the rks of the Rgveda. The last 3 prapathakas (10-12) of the 3rd Kanda of the Taittiriya brahmana is termed as 'Kathaka' brahmana by the Yajurvedis leading to a conjecture that this portion probably belonged to the Kathaka brahmana and has been enjoined here with a specific purpose. The Taittiriya brahmana also has references to many tenets of Vaidik Jyotish thereby giving the text a prime importance.

The Kathaka brahmana is only known by its mention, not available as a text.

Aranyakas

Baldev Upadhyay (1955), Vaidik Sahitya, Kashi

There are two Aranyakas belonging to the Yajurveda viz.

1. Brhadaranyaka belonging to the Shukla Yajurveda
2. Taittiriya Aranyaka belonging to the Krshna Yajurveda

As the name suggests, Brhadaranyaka is an Aranyaka. However, due to a detailed discussion on the atmatattva, it is considered an Upanishad. That too an ancient and important one at that. It appears at the end of the Shatapatha Brahmana.

The Maitrayani shakha of the Krshna Yajurveda also has an Aranyaka that is known as Maitrayani Upanishad.

The Taittiriya Aranyaka consists of 10 Paricchedas or Prapathakas that are generally termed as Aranas and are named after the first word occuring in them. Accordingly, their names are,

1. Bhadra
2. Sahavai
3. Chitti
4. Yunjate
5. Devavai
6. Pare
7. Shiksha
8. Brahmavidya
9. Bhrgu
10. Narayaniya

Of these, the 7th, 8th and 9th Prapathakas together are termed as Taittiriya Upanishad and the 10th Prapathaka is known as the Mahanarayaniya Upanishad and is considered a Parishishta of the Taittiriya Aranyaka. The Prapathakas are further divided into Anuvakas numbering to 170 until the 9th Prapathaka. And the anuvakas are organised into dashakas. This Aranyaka has good number of rks quoted from the Rgveda.

Upanishads

Baldev Upadhyay (1955), Vaidik Sahitya, Kashi

According to the Muktikopanishad, the total number of Upanishads is 108 out of which 19 are related to the Shukla Yajurveda and 12 are related to the Krshna Yajurveda. However, the 10 Upanishads on which Shankaracharya wrote his commentary are considered ancient most and important. They include Isha, Kena, Katha, Prashna, Munda, Mandukya, Tittiri, Aitareya, Chandogya and Brahadaranyaka. Apart from these, Kaushitaki, Shvetashvatara and Maitrayani are also considered ancient.

Brihadaranyaka Upanishad

It is key scripture of Hinduism that has influenced all schools of Hindu philosophy. The text is a treatise on Ātman (Soul, Self), with passages on metaphysics, ethics and a yearning for knowledge that influenced various Indian religions, ancient and medieval scholars.

Isha Upanishad

The Isha Upanishad discusses the Atman (Soul, Self) theory of Hinduism, and is referenced by both Dvaita (dualism) and Advaita (non-dualism) sub-schools of Vedanta.

Taittiriya Upanishad

It is the seventh, eighth and ninth chapters of Taittiriya Aranyaka, which are also called, respectively, the Siksha Valli, the Ananda Valli and the Bhrigu Valli.

Katha Upanishad

The detailed teachings of Katha Upanishad have been variously interpreted as Advaita (non-dualistic).

Shvetashvatara Upanishad

Maitrayaniya Upanishad

Shiksha

Every Veda has its own Shiksha grantha that enumerates the rules of phonetics specific to that Veda. The Pratishakhya texts are the oldest available shiksha granthas. There are two Pratishakhya texts available in the Yajurveda tradition viz. Vajasaneyi Pratishakhya and Taittiriya Pratishakhya.

As the name suggests, the Vajasaneyi Pratishakhya is related to the Shukla Yajurveda and is written by Katyayana Muni who is different from the Vartikakara Katyayana (Vararuchi) and preceeds Panini. This Pratishakhya (also known as Katyayana Pratishakhya) texts consists of 8 adhyayas that includes a detailed discussion on Paribhasha, Svara and Samskara. It is for this reason that Katyayana is given the title स्वरसंस्कारप्रतिष्ठापयिता । (८.५४) A study of the text reveals that Panini has taken Paribhashika terms like Upadha, Udatta, Anudatta, Svarita, Amredita, Lopa, Aprkta, etc. for his Grammar from this Pratishakhya text. Many sutras have also been accepted by Panini verbatim.

There are two commentaries available on the Katyayana Pratishakhya by Uvvata and Ananta Bhatta. The one by Anantabhatta is known as Padartha Prakasha. There are also two other small texts related to the Katyayana Pratishakhya that are available along with their respective bhashyas. These are considered as the Parishishtas of the Katyayana Pratishakhya viz. Pratijna Sutra and Bhashika Sutra.

The Taittiriya Pratishakhya is divided into 2 Prashnas (Khandas) each consisting of 12 adhyayas each. All the examples quoted in this Pratishakhya are from the Taittiriya Samhita. There are 3 commentaries available on the Taittiriya Pratishakhya viz.

1. Padakramasadana by Mahisheya
2. Tribhashya Ratna by Somayaarya
3. Vaidikabharana by Gopala Yajva (also known as Gopala Mishra)

The essence of the different subject-matters of the Pratishakhyas were condensed and presented in the form of a collection of Karikas that came to be known as shiksha granthas. They are related to the various branches of the four vedas. The Shiksha texts related to the Yajurveda are enumerated below:

Yajnavalkya Shiksha: It consists of 232 shlokas and is related to the Vajasaneyi Samhita (Madhyandina Samhita) of the Shukla Yajurveda. It elaborates with examples on Vadika Svaras. It also discusses concepts like lopa, agama, vikara and prakrti bhava. The nature, similarities and differences among letters have also been explained.

Vasishti Samhita: It is related to the Vajasaneyi Samhita of the Shukla Yajurveda. According to this shiksha, the number of rgveda mantras occuring in the shukla Yajurveda is 1467 while the total number of Yajus is 2823.

Mandavya Shiksha: It is related to the Shukla Yajurveda. In this shikshsa there is a collection of the Oshthya varnas featuring in the Vajasaneyi Samhita.

यजुर्वेदीयकल्पसूत्राणि ॥ Kalpa Sutras

Kalpa sutras are texts that enumerate the procedures involved in Vedic rituals in their designated order. They are of four types viz. Shrauta sutras (dealing with elaborate Yajnas), Grhya sutras (dealing with smaller Yagas and Samskaras), Dharma sutras (dealing with Varnashrama dharmas), Shulbasutras (dealing with construction of Yajna Vedis).

Shukla Yajurvedic Kalpa sutras:

There is only one Shrautasutra belonging to the Shukla Yajurveda viz. Katyayana Shrautasutra. Consisting of 26 adhyayas, it elaborates on the Yajnas described in the Shatapatha brahmana. Karkacharya's bhashya on this text is considered important.

The only Grhayasutra belonging to the Shukla Yajurveda is known as Paraskara Grhyasutra. Consisting of 3 Kandas, it describes the Samskaras in detail and is endowed with 5 commentaries by Karka, Jayarama, Harihara, Gadadhara and Vishvanatha.

The Katyayana Shraddha Sutra, also known as Katiya Shraddha Sutra, elaborates on shraddha and consists of 9 Kandikas. It is commented upon by Karkacharya, Gadadhara and Krishna Mishra. A commentary of Halayudha is mentioned in the beginning of shraddha Kashika by Krishna Mishra.

The Shulbasutras of Katyayana consist of 7 Kandikas and discusses about construction of Yajna Vedis, quadrilateral area, etc. reflecting Vedic geometry.

Krishna Yajurvedic Kalpa Sutras:

The Taittiriya Shakha has 5 Shrauta sutras viz. Baudhayana, Apastamba, Hiranyakeshi or Satyashadha, Vaikhanasa and Bharadvaja Shrauta sutra while the Maitrayani shakha has the Manava Shrauta sutra. Of these, the Baudhayana and Manava shrauta sutra are older as they are mentioned in the Apastamba shrauta sutra.

Infact the Baudhyana and Apastanba traditions have all the 4 types of Kalpa sutras viz. Shrauta, Grhya, Dharma and Shulba. They are so interconnected that it seems like they are 4 parts of the same text.

The Hiranyakeshi or Satyashadha, Bharadvaja and Manava traditions have shrauta and grhya sutra texts.

There is also a Kathaka Grhyasutra belonging to the Katha Shakha of the Krshna Yajurveda. It is also known as Laugakshi Grhya sutra. It is organised in two ways either as 73 kandikas or as 5 adhyayas. Due to the Panchadhyaya division, it is also known as Grha-Panchika and is endowed with three commentaries by Adityadarshana (the oldest), Brahmanabala (son of Madhavarya) and Devapala (son of Haripala).

There is also a small text by the name Varaha shrautasutra related to the Krshna Yajurveda that gives a simple enunciation of shrauta yagas.

The dharmasutras for Ashvalayana, shankhayana and Manava traditions are not available. The Baudhayana, Apastamba and Hiranyakeshi have their dharmasutra texts.

Vedanga Jyotish

Every element of time like Nakshatra, Tithi, Paksha, Masa, Rtu and Samvatsara are connected to the conjunctions of Vedic rituals. And in order to follow the vedic injuctions it is essential to have knowledge of Jyotish. There are two texts of Vedanga Jyotish available viz.

1. Yajusha Jyotish related to the Yajurveda
2. Acharya Jyotish related to the Rgveda

Yajusha Jyotish consists of 43 shlokas.

पदकाराः ॥ Padapatha Authors

The padapatha of Yajurveda Samhitas are available though not all are published. While the padapatha of Madhyandina Samhita is published, the padapatha for Kanva Samhita is not published. However, there are no details available about their authors.

The author of the padapatha of Taittiriya Samhita is Atreya and this is mentioned by Bhatta Bhaskara in the beginning of his commentary on the Taittiriya Samhita.

उखश्चात्रेयाय ददौ येन पदविभागश्चक्रे ।

The Kandanukramani also mentions Atreya as the author of the Taittiriya padapatha.

यस्याः पदकृदात्रेयो वृत्तिकारस्तु कुण्डिनः ।

The Bodhayana Grhyasutra mentions tarpana for Padakara Atreya in the performance of Rishi tarpana c.f. आत्रेयाय पदकाराय ३.९.७

This Atreya is contemporary to the Rigveda Padakara Shakalya.

भाष्यकाराः ॥ Commentators

In the medieval times, the Vaidik scholars wrote commentaries on the Vaidik Samhitas in order to bring forth their meaning and make them more understandable. And they put to use knowledge of nirukta, grammar, puranas, itihasas, etc in this process of semantic pursuit.

The commentators of the Yajurveda Samhitas are as follows:

1. Taittiriya Samhita - Bhavasvami, Guhadeva, Kshura and Bhatta Bhaskara Mishra.
2. Madhyandina Samhita - Uvvata and Mahidhara

Swami Dayananda Saraswati has also written Samskrit commentaries on the Yajurveda.

Baldev Upadhyay (1955), Vaidik Sahitya, Kashi

Manuscripts and translations

Devi Chand published a re-interpreted translation of Yajurveda in 1965, reprinted as 3rd edition in 1980, wherein the translation incorporated Dayananda Saraswati's monotheistic interpretations of the Vedic text, and the translation liberally adds "O Lord" and "the Creator" to various verses, unlike other translators.

Sripad Damodar Satavlekar published the Yajuevedic Samhita with an index. A hindi translation of the Yajurveda Samhita by Acharya Shriram Sharma is available.

Baldev Upadhyay (1955), Vaidik Sahitya, Kashi

Rtvik

Apte

अध्वर्युः. Any officiating priest, technically distinguished from होतृ, उद्रातृ and ब्रह्मन्. His duty was "to measure the ground, build the altar, prepare sacrificial vessels, to fetch wood and water, to light the fire, to bring the animal and immolate it," and while doing this to repeat the Yajurveda; होता प्रथमं शंसति तमध्वर्युः प्रोत्साहयति Sk. See अच्छावाक also.

The Yajurveda Samhita was compiled keeping in mind the procedural principles of Yajnas. And among the four rtviks imperative to the fulfilment of Yajna-karmas, the Adhvaryu is of prime importance as he fulfils the prime rituals of the Yajna. And it is to aid the fulfilment of his specific duties known as the Adhvaryava that the Yajurveda Samhitas are compiled within different shakhas. The adhvaryu recites the prosaic mantras or yajus and performs the rituals.

Concept of Rna

It is said that the term Rna first occured in the Rgveda. And the concepts of Deva Rna and Pitr Rna took birth. In the Yajurveda, we find that the concept of Rshi Rna gets added and the number of Rnas become three.

5 उत्तमो हि प्राणो यदीतरं यदीतरम् उभयम् एवाजामि जायमानो वै ब्राह्मणस् त्रिभिर् ऋणवा जायते ब्रह्मचर्येणर्षिभ्यो यज्ञेन देवेभ्यः प्रजया पितृभ्य एष वा अनृणो यः पुत्री यज्वा ब्रह्मचारिवासी तद् अवदानैर् एवाव दयते तद् अवदानानाम् अवदानत्वम् । देवासुराः संयत्ता आसन् ते देवा अग्निम् अब्रुवन् त्वया वीरेणासुरान् अभि भवामेति । (Taittiriya Samhita 6.3.10.5)
