Source: Cologne Digital Sanskrit Dictionaries: The Purana IndexAtyaṣṭi (अत्यष्टि).—A poetic metre.*
- * Bhāgavata-purāṇa XI. 21. 41.

The Purana (पुराण, purāṇas) refers to Sanskrit literature preserving ancient India’s vast cultural history, including historical legends, religious ceremonies, various arts and sciences. The eighteen mahapuranas total over 400,000 shlokas (metrical couplets) and date to at least several centuries BCE.
Natyashastra (theatrics and dramaturgy)
Source: Wisdom Library: Nāṭya-śāstraAtyaṣṭi (अत्यष्टि) refers to a class of rhythm-type (chandas) containing seventeen syllables in a pāda (‘foot’ or ‘quarter-verse’), according to the Nāṭyaśāstra chapter 15. There are twenty-six classes of chandas and out of them arise the various syllabic meters (vṛtta), composed of four pādas, defining the pattern of alternating light and heavy syllables.

Natyashastra (नाट्यशास्त्र, nāṭyaśāstra) refers to both the ancient Indian tradition (shastra) of performing arts, (natya—theatrics, drama, dance, music), as well as the name of a Sanskrit work dealing with these subjects. It also teaches the rules for composing Dramatic plays (nataka), construction and performance of Theater, and Poetic works (kavya).
Vyakarana (Sanskrit grammar)
Source: Wikisource: A dictionary of Sanskrit grammarAtyaṣṭi (अत्यष्टि).—A variety of Aticchandas metre consisting of 68 syllables. e. g. अथा रुचा हरिण्या पुनानः (athā rucā hariṇyā punānaḥ) Ṛk. Sam. 8.111.1.

Vyakarana (व्याकरण, vyākaraṇa) refers to Sanskrit grammar and represents one of the six additional sciences (vedanga) to be studied along with the Vedas. Vyakarana concerns itself with the rules of Sanskrit grammar and linguistic analysis in order to establish the correct context of words and sentences.
Chandas (prosody, study of Sanskrit metres)
Source: Shodhganga: a concise history of Sanskrit Chanda literatureAtyaṣṭi (अत्यष्टि) is one of the twenty-six varieties of Sanskrit metres (chandas) mentioned in the Chandaśśāstra 1.15-19. There are 26 Vedic metres starting with 1 to 26 letters in each pāda. It is a common belief that the classical metres are developed from these 26 metres. Generally a metre has a specific name according to it’s number of syllables (akṣara). But sometimes the same stanza is called by the name of another metre from the point of view of the pādas.

Chandas (छन्दस्) refers to Sanskrit prosody and represents one of the six Vedangas (auxiliary disciplines belonging to the study of the Vedas). The science of prosody (chandas-shastra) focusses on the study of the poetic meters such as the commonly known twenty-six metres mentioned by Pingalas.
Ganitashastra (Mathematics and Algebra)
Source: archive.org: Hindu MathematicsAtyaṣṭi (अत्यष्टि) represents the number 17 (seventeen) in the “word-numeral system” (bhūtasaṃkhyā), which was used in Sanskrit texts dealing with astronomy, mathematics, metrics, as well as in the dates of inscriptions and manuscripts in ancient Indian literature.—A system of expressing numbers by means of words arranged as in the place-value notation was developed and perfected in India in the early centuries of the Christian era. In this system the numerals [e.g., 17—atyaṣṭi] are expressed by names of things, beings or concepts, which, naturally or in accordance with the teaching of the Śāstras, connote numbers.

Ganita (गणित) or Ganitashastra refers to the ancient Indian science of mathematics, algebra, number theory, arithmetic, etc. Closely allied with astronomy, both were commonly taught and studied in universities, even since the 1st millennium BCE. Ganita-shastra also includes ritualistic math-books such as the Shulba-sutras.

The history of India traces the identification of countries, villages, towns and other regions of India, as well as mythology, zoology, royal dynasties, rulers, tribes, local festivities and traditions and regional languages. Ancient India enjoyed religious freedom and encourages the path of Dharma, a concept common to Buddhism, Hinduism, and Jainism.
