In Hinduism
Shaktism (Shakta philosophy)
Source: Google Books: ManthanabhairavatantramRātri (रात्रि) or Niśā refers to the “night”, according to the Tantrāloka verse 8.422.—The day is the domain of daily life. It is the auspicious domain of creation and stability and of the sacred forces and beings who sustain it. Conversely, night is the domain of destructive forces and the deluding darkness of slumber. Māyā is the Night (niśā, rātri), the dark night of ignorance. However, Māyā is also the goddess who is made of the night (niśāmayā). Māyā, the Night, has two faces. The night of ignorance for the worldly, fettered soul is the day of awakening for the wise. Śiva, inactive like a corpse, is immersed in contemplation (samādhi) ‘at night’ when he is free of Māyā. His is the Practice of Stillness (nirācāra)—the realisation of the extinction—nirvāṇa—of all limitations and afflictions through the rise of Kuṇḍalinī brought about by his Practice at Night (niśācāra).
Source: Red Zambala: The 10 Great Wisdom GoddessesThe word Rātri (night) is symbolically derived from the root rā “to give,” and is taken to mean “the giver” of bliss, of peace, of happiness.

Shakta (शाक्त, śākta) or Shaktism (śāktism) represents a tradition of Hinduism where the Goddess (Devi) is revered and worshipped. Shakta literature includes a range of scriptures, including various Agamas and Tantras, although its roots may be traced back to the Vedas.
Purana and Itihasa (epic history)
Source: Wisdom Library: Varāha-purāṇa1) Rātrī (रात्री).—Name of a river originating from Ṛkṣa, a holy mountain (kulaparvata) in Bhārata, according to the Varāhapurāṇa chapter 85. There are settlements (janapada) where Āryas and Mlecchas dwell who drink water from these rivers.
Bhārata is a region south of Hemādri, once ruled over by Bharata (son of Ṛṣabha), whose ancestral lineage can be traced back to Svāyambhuva Manu.
2) Rātrī (रात्री).—One of the seven major rivers situated in Krauñcadvīpa, according to the Varāhapurāṇa chapter 88. It is also known by the name Sukhāvahā. Krauñcadvīpa is one of the seven islands (dvīpa), ruled over by Jyotiṣmān, one of the ten sons of Priyavrata, who is the son of Svāyambhuva Manu.
Svāyambhuva Manu, who was created by Brahmā, who was in turn created by Nārāyaṇa, the unknowable all-pervasive primordial being.
The Varāhapurāṇa is categorised as a Mahāpurāṇa, and was originally composed of 24,000 metrical verses, possibly originating from before the 10th century. It is composed of two parts and Sūta is the main narrator.

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.
Vaishnavism (Vaishava dharma)
Source: Pure Bhakti: Bhajana-rahasya - 2nd EditionRātri (रात्रि) refers to:—Night. (cf. Glossary page from Bhajana-Rahasya).

Vaishnava (वैष्णव, vaiṣṇava) or vaishnavism (vaiṣṇavism) represents a tradition of Hinduism worshipping Vishnu as the supreme Lord. Similar to the Shaktism and Shaivism traditions, Vaishnavism also developed as an individual movement, famous for its exposition of the dashavatara (‘ten avatars of Vishnu’).
Shaivism (Shaiva philosophy)
Source: SOAS University of London: Protective Rites in the Netra TantraRātri (रात्रि) refers to the “night”, 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 19.94cd-99ab, while describing the ritual that protect the king and his kingdom]—“[...] Great sleep, who bewilders the world, is there. For the king’s well-being at night and for his digestion when he eats, etc., this worship should continue [throughout the night] by the order of the God of Gods. Then [the king] should sleep the entire night (rātri—tato rātriṃ samagrāṃ). He should remain at ease, free of the dangers of Yakṣas, Rakṣas, Pisācas, fear of disrupted sleep—which bring about Mātṛs—and trembling from those afflictions”.

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.
Yoga (school of philosophy)
Source: ORA: Amanaska (king of all yogas): A Critical Edition and Annotated Translation by Jason BirchRātri (रात्रि) refers to the “day”, according to the the Amanaska Yoga treatise dealing with meditation, absorption, yogic powers and liberation.—Accordingly, as Īśvara says to Vāmadeva: “[...] The Yogin should not wake by day and should not sleep even for a fraction of the night (rātri). Night and day, the Yogin always sleeps in the natural [no-mind] state. For a man who remains in the pure, natural [no-mind state], there is not even the distinction of day and night, because [that] place is the bliss of mere consciousness, which is free from wakefulness and sleep. [...]”.

Yoga is originally considered a branch of Hindu philosophy (astika), but both ancient and modern Yoga combine the physical, mental and spiritual. Yoga teaches various physical techniques also known as āsanas (postures), used for various purposes (eg., meditation, contemplation, relaxation).
In Buddhism
Mahayana (major branch of Buddhism)
Source: academia.edu: A Study and Translation of the GaganagañjaparipṛcchāRātri (रात्रि) refers to the “night” (when the Tathāgata attained awakening), according to the Gaganagañjaparipṛcchā: the eighth chapter of the Mahāsaṃnipāta (a collection of Mahāyāna Buddhist Sūtras).—Accordingly, “How, then, son of good family, does the Bodhisattva grasp the treasury of the dharma jewel of the Awakened Lords? [...] From the night (rātri) when the Gathāgata attained awakening (bodhi) to the night of his extinction (parinirvāṇa), the treasury of the dharma jewel has been explained, is being explained, and will be explained by the Tathāgata. All of them are what they really are (tathatā), not different from what they are (avitathatā), and nothing else but what they are (ananyathā). [...]”.

Mahayana (महायान, mahāyāna) is a major branch of Buddhism focusing on the path of a Bodhisattva (spiritual aspirants/ enlightened beings). Extant literature is vast and primarely composed in the Sanskrit language. There are many sūtras of which some of the earliest are the various Prajñāpāramitā sūtras.
