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.
Purana and Itihasa (epic history)
Source: archive.org: Shiva Purana - English TranslationTatkṣaṇa (तत्क्षण) refers to an “instant” (i.e., ‘to arrive in an instant’), according to the Śivapurāṇa 2.3.17 (“The dialogue between Indra and Kāmadeva”).—Accordingly, as Brahmā narrated: “When the gods had gone, Indra remembered Kama. He was so afflicted by Tāraka, the wicked demon. In an instant [i.e., tatkṣaṇa], Kāma, the lover of Rati, came there along with Vasanta. He was accompanied by Rati too. Being powerful enough to conquer the three worlds he was very haughty. Making due obeisance standing in front of Indra, the lofty-minded Kāma joined his palms in reverence and said:—[...]”.

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.
Shaivism (Shaiva philosophy)
Source: SOAS University of London: Protective Rites in the Netra TantraTatkṣaṇa (तत्क्षण) means “at that very moment”, according to the Netratantra of Kṣemarāja: a Śaiva text from the 9th century in which Śiva (Bhairava) teaches Pārvatī topics such as metaphysics, cosmology, and soteriology.—Accordingly, [verse 6.15cd-20]—“[...] When a man is seen to be afflicted with 100 diseases [and] weak, [he] is released [when the Mantrin] envelops his name [with the mṛtyuñjayamantra] and recites [it]. Any mantra that a wise man should recite, is enveloped by Amṛteśa. This mantra quickly [brings] him success, even if he is without good fortune. [The Mantrin] envelops medicine [consisting of herbs] with the Mantra. [He then] gives [the mantra wrapped medicine] to [the person whose] body is weak. At that very moment (tatkṣaṇa), his body gains nourishment and [becomes] strong”.

Shaiva (शैव, śaiva) or Shaivism (śaivism) represents a tradition of Hinduism worshiping Shiva as the supreme being. Closely related to Shaktism, Shaiva literature includes a range of scriptures, including Tantras, while the root of this tradition may be traced back to the ancient Vedas.
In Buddhism
Tibetan Buddhism (Vajrayana or tantric Buddhism)
Source: OSU Press: Cakrasamvara SamadhiTatkṣaṇa (तत्क्षण) refers to “each moment”, according to the Guru Mandala Worship (maṇḍalārcana) ritual often performed in combination with the Cakrasaṃvara Samādhi, which refers to the primary pūjā and sādhanā practice of Newah Mahāyāna-Vajrayāna Buddhists in Nepal.—Accordingly, “Charity (is) cow dung and water united, moral conduct and cleansing, Patience, taking away tiny ants, heroism, bringing forth the religious rite. Meditation, single-minded in each moment (tatkṣaṇa), wisdom, splendidly clear lines, These perfections, six indeed are gained, having made the Muni’s maṇḍala”.

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.
