== Introduction ==
Grhyasutras belong to the class of Kalpasutra texts. Kalpas are important texts of [[Shad Vedangas (षड्वेदाङ्गानि)|six vedangas]], the ancilliary subjects which are required to understand Vedas and hence are one among the Chaturdasha Vidyas. They pertain to domestic rituals as known from the word Grhya. Thus the subject matter of grhyasutras involves the domestic life of a person.
The origin of the Grhyasutras appear to be traceable to an oral tradition prevalent among the people of ancient times which preserved them till date. They employ many mantras from the veda samhita parts while performing the domestic rituals. So one can understand the antiquity of these ceremonies which are traced back to the time of the Vedas.
== Subject-matter of Grhyasutras ==
[[Samskaras (संस्काराः)|Samskaras]] form an important subject of the Grhyasutras. Broadly topics treated in these texts include pre-birth ceremonies for the mother Pumsavana, Seemantonnayana etc) and post-birth ceremonies of the child starting from Namakarana, a detailed account of [[Upanayana (उपनयनम्)|Upanayana]], Upakarma, [[Samavartana (समावर्तनम्)|Samavartana]], [[Snataka (स्नातकः)|Snataka]] conduct
up to Antyeshti or the funeral ceremonies. The Grhyasutras give a detailed account of the ceremony of Upanayana and other education related samskaras which a child undergoes starting from initiation into the study of Veda. Being the pivot of all domestic ceremonies, the marriage with its diverse and diffuse details occupies a great deal of explanation in the Grhyasutras.
The daily obligatory activities of a grhastha such as [[Panchamahayajnas (पञ्चमहायज्ञाः)|Panchamahayajnas]], Pakayajnas and the periodical yajnas, [[Shraddha (श्राद्धम्)|shraddha]], monthly rituals to be performed on the new-moon and full-moon days, annual rituals among other information. The yajnas that are performed annually include Sravana, the Indrayajna, the Asvayuji, the Agrahayani, the Ashtakas, the Phalguni, and the Chaitriyajna.
Apart from the above, these texts contain ceremonies connected with agricultural operations, cattle welfare and festivities associated with them. The ceremony of Vrshotsarga, wherein a stud-bull is
stamped and left at liberty, is discussed, so also the Sulagava yajna for the prosperity of cattle. Mantras which are to be recited while driving cattle to and fro from pasture. Ploughing the field is started with special ceremonies as is the Sita (which literally means a furrow) worshipped. Agrayana yajna is connected with agriculture wherein the first fruits of the crop are to be offered to the deities.
Next topic of importance discussed in the Grhyasutras includes the choice of land for building a house, the rites to be performed for laying the foundation and the main door or gate of the house, and when the pujas to be performed when the owner first enters the house after its completion.

Like the Vedas, Grhyasutras are also handed down and preserved since ancient times through oral tradition. Transmission of what was studied, memorized and practiced manifested as the tradition or custom, which, was regarded as an authority of these rituals. This was the foundation of Sampradayas which are the existing authorities in matters pertaining to Bharatiya culture and dharmas.
=== '''पाकयज्ञः''' Pakayajna === The term Pakayajnas is used to refer to Grhyayajnas to distinguish them from the Shrauta yajnas. This point has been mentioned in Brahmana texts of the Vedas.<blockquote>...'''पाकयज्ञा''' इळामेवानु ये केच '''पाकयज्ञास्ते''' सर्वेऽग्निष्टोममपियन्ति सायम्प्रातरग्निहोत्रं जुह्वति सायम्प्रातर्व्रतम्प्रयछन्ति स्वाहाकारेणाग्निहोत्रं जुह्वति...। (Aite.
