Earliest instances of methodical composition of knowledge base can be seen in the Anukramanikas.  They are associated with Vedic texts and are the scientific indices on the vedic mantras. Each Veda contains atleast one such index. Because of Anukramanikas the texts have been preserved and tradition continued. These indices are very systematic recording the exact number of mantras, even aksharas, such that no scope for interpolation or deletion was allowed preserving the text accurately.<ref>''The Role of Tantrayuktis in Indian Research Methodology'' by Komatineni Surendra and J.S.

While almost all the above mentioned texts discussed tantrayukti, Arunadatta, the commentator of Vagbhata's Ashtangahrdayam, has dealt with explanation for a large number of devices other than the tantrayuktis.

=== व्याख्या ॥ Vyakhya ===

Vyakhya has been defined as विवरणात्मकशब्दसमूहरूपोग्रन्थविशेषः। meaning a particular composition explanatory in nature. Arunadatta in his Sarvanga Sundara commentary for Ashtangahrdayam explains thus <blockquote>व्याख्या अपि तन्त्रस्य गुणः। ताभिरपि तन्त्रमलङि्क्रयते । ताश्च पञ्चदश प्रकारा । vyākhyā api tantrasya guṇaḥ। tābhirapi tantramalaṅikrayate । tāśca pañcadaśa prakārā । </blockquote>Meaning:  An explanation (or exposition or commentary) is also an attribute (a desirable property) of a scientific composition.

Kalpana (कल्पना) means the use of a word in a secondary sense.

# '''प्रधानेन कल्पना ॥ pradhānēna kalpanā''' is defined as प्रधानेन तु कल्पना यथा - क्षीरदधितक्र... सर्वः क्षीरवर्ग इत्युक्तः क्षीरप्राधान्यात् । pradhānena tu kalpanā yathā - kṣīradadhitakra... sarvaḥ kṣīravarga ityuktaḥ kṣīraprādhānyāt । Pradhana Kalpana is a method which is used to name a group of substances after one of them which predominantly possesses the common property. For example, there is a predominance of milk in milk, curds, buttermilk, butter, ghee etc, all these things are said to belong to the milk-group. This device follows the Nyaya ' प्रधानेन व्यपदेशा भवन्ति ' which the ancient thinkers commonly followed and is an important Kalpana.

# '''परतन्त्रप्रत्ययः ॥ paratantrapratyayaḥ''' is defined as परतन्त्रप्रत्ययो नाम, - यस्यार्थस्य प्रसिद्धितो न स्वकीयमुदाहरणं शक्यमभिधातुं नाप्यन्येभ्यो भिषक्तन्त्रेभ्यः ।  ततस्तस्मिन्द्वये परतन्त्रादुदाहरणं कल्प्यते ।  paratantrapratyayo nāma, - yasyārthasya prasiddhito na svakīyamudāharaṇaṁ śakyamabhidhātuṁ nāpyanyebhyo bhiṣaktantrebhyaḥ । tatastasmindvaye paratantrādudāharaṇaṁ kalpyate । When a shastra concept is such that it cannot be explained clearly with the help of one's treatise, or another author's treatise belonging to the same branch of learning, then the explanation is attempted using the concepts presented in a different discipline. Poetics are abundant with examples of such type of compositions.

# '''हेतुहेतुकधर्मः ॥ hetuhetukadharmaḥ''' is defined as यो हेतुहेतुकधर्मो नाम, - यो हेतुहेतुकेन धर्मो ज्ञायते । yo hetuhetukadharmo nāma, - yo hetuhetukena dharmo jñāyate । Hetu means a major or potential cause; Hetuka means a minor or incidental cause. To make an inference of the dharma or the common property after reading or hearing both the Hetu and hetuka is called the Hetuhetukadharma Ashraya. It is to be kept in mind that Hetu unfailingly brings about the effect. This concept support system helps the reader draw a line of demarcation between the major and minor causes of an effect and thus finds place as an important  consideration in building the methodology of a text.

Tatchilya is an informal use of a word in a scientific or poetic composition. In common language, people normally use words with extending, stretching or even twisted meanings, implying them to describe other situations, actions than they were originally meant for. This is the metaphorical process and in essence means transfer of meaning of a word to an entirely different context or situation. For example : we say 'In the eyes of law she was guilty and punished', here we mean in the 'view of law', since law, an inanimate thing cannot have eyes, and its action of viewing is extended to law. But such usages are very common and many times are used to enhance poetic beauty.

# '''गुणनिमित्तता ॥ guṇanimittatā''' is defined as  गुणनिमित्तं नाम, - यत्कस्य विभूतिः प्रशंसादिका ख्यार्यते। guṇanimittaṁ nāma, - yatkasya vibhūtiḥ praśaṁsādikā khyāryate। To name something after a praiseworthy quality in it. For example, observance of celibacy helps one achieve righteousness, fame, long life and utmost purity. Considering this if one calls Brahmacharya itself as धर्म्य, यशस्य, आयुष्य, etc one will be said to be using गुणनिमित्तता

Yet the comparison is made taking into account one characteristic that is common both to lamp and knowledge which is prakashana the action of light.
