In Hinduism
Purana and Itihasa (epic history)
Mahānidrā (महानिद्रा) refers to the “supreme slumber”, according to the Śivapurāṇa 2.3.4.—Accordingly, as the Gods eulogized Umā (Durgā/Satī) with devotion:—“[...] thus eulogised by the Gods, the Goddess Durgā, the mother of the universe, the destroyer of impassable distress, appeared in front of them. [...] She was the mother of the three deities, Caṇḍī, Śivā, the destroyer of the distress of all, the mother of all supreme slumber (i.e., mahānidrā) and the redeemer of all her own people”.

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)
Mahānidrā (महानिद्रा):—Excessive sleep

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.
Shaivism (Shaiva philosophy)
Mahānidrā (महानिद्रा) refers to “great sleep”, 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 (mahānidrā), 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. 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.
