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.
Ayurveda (science of life)
Nighantu (Synonyms and Characteristics of Drugs and technical terms)
Source: WorldCat: Rāj nighaṇṭuNīlaka (नीलक) is another name for Nīlabhṛṅgarāja, which is the blue/black variety of Mārkava, a medicinal plant identified with Eclipta nigra, according to verse 4.138-141 of the 13th-century Raj Nighantu or Rājanighaṇṭu. The fourth chapter (śatāhvādi-varga) of this book enumerates eighty varieties of small plants (pṛthu-kṣupa). Together with the names Nīlaka and Mārkava, there are a total of twenty Sanskrit synonyms identified for this plant. Note: R. P. T. claims he himself has seen its miraculous effect in normalising blood pressure and its rejuvenating effect.

Āyurveda (आयुर्वेद, ayurveda) is a branch of Indian science dealing with medicine, herbalism, taxology, anatomy, surgery, alchemy and related topics. Traditional practice of Āyurveda in ancient India dates back to at least the first millenium BC. Literature is commonly written in Sanskrit using various poetic metres.
Ganitashastra (Mathematics and Algebra)
Source: archive.org: Hindu MathematicsNīlaka (नीलक) or Nīla refers to the “color blue” which were used as symbols for the unknowns, according to the principles of Bījagaṇita (“algebra” or ‘science of calculation’), according to Gaṇita-śāstra, ancient Indian mathematics and astronomy.—Āryabhaṭa I (499) very probably used coloured shots to represent unknowns. Brahmagupta (628) in the Brāhmasphuṭasiddhānta mentions varṇa as the symbols of unknowns. As he has not attempted in any way to explain this method of symbolism, it appears that the method was already very familiar. [...] In the case of more unknowns, it is usual to denote the first yāvattāvat and the remaining ones by alphabets or colours [e.g., nīlaka].—Cf. Pṛthūdakasvāmī (860) in his commentary on the Brāhmasphuṭasiddhānta by Brahmagupta (628) and Bhāskara II in the Bījagaṇita.

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.
In Buddhism
Tibetan Buddhism (Vajrayana or tantric Buddhism)
Source: MDPI Books: The Ocean of HeroesNīlaka (नीलक) refers to a “dark-blue (color)”, according to the 10th-century Ḍākārṇava-tantra: one of the last Tibetan Tantric scriptures belonging to the Buddhist Saṃvara tradition consisting of 51 chapters.—Accordingly, [while describing the Merit Circle (guṇacakra)]: “[...] He should make [mantras of all Yoginīs] on all circles [in this manner]. Outside that, he should give a circle, [on which there are] two lines [colored] black and dark blue (kṛṣṇa-nīlaka). Gates, arched doorways, and altars are [on the circle], adorned with garlands of pearls and half-garlands of pearls. [...] Two colors should be evenly assigned [to them] in accordance with the [directions they] face, respectively. [...]”.

Tibetan Buddhism includes schools such as Nyingma, Kadampa, Kagyu and Gelug. Their primary canon of literature is divided in two broad categories: The Kangyur, which consists of Buddha’s words, and the Tengyur, which includes commentaries from various sources. Esotericism and tantra techniques (vajrayāna) are collected indepently.
