Brahmanas in the context of "Adityas"

Śruti or shruti (Sanskrit: श्रुति, IAST: Śruti, IPA: [ɕruti]) in Sanskrit means "that which is heard" and refers to the body of most authoritative, ancient religious texts comprising the central canon of Hinduism. Manusmriti states: Śrutistu vedo vijñeyaḥ (Devanagari: श्रुतिस्तु वेदो विज्ञेयः) meaning, "Know that Vedas are Śruti". Thus, it includes the four Vedas including its four types of embedded texts—the Samhitas, the Upanishads, the Brahmanas and the Aranyakas.

Śrutis has been variously described as a revelation through anubhava (direct experience), or of primordial origins realized by ancient Rishis. In Hindu tradition, they have been referred to as apauruṣeya (not created by humans). The Śruti texts themselves assert that they were skillfully created by Rishis (sages), after inspired creativity, just as a carpenter builds a chariot.

The Saptarshi (Sanskrit: सप्तर्षि, lit. 'Seven sages' IAST: Saptarṣi) are the seven seers of ancient India who are extolled in the Vedas, and other Hindu literature such as the Skanda Purana. The Vedic Samhitas never enumerate these rishis by name, although later Vedic texts such as the Brahmanas and Upanisads do, so these constellations are easily recognizable.

Ratri (Sanskrit: रात्रि, lit. 'night', IAST: Rātri; also referred to as Nisha), is a Vedic goddess in Hinduism. She is the personification of the night. The majority of references to Ratri are found in Rigveda and she is described as the sister of Ushas, the personification of dawn. Together with Ushas, she is referred to as a powerful mother and strengthener of vital power. She represents cyclic rhythmic patterns of the cosmos. Her physical appearance isn't explicitly mentioned, but she is described as a beautiful maiden.

One hymn in the Rigveda and five hymns in the Atharvaveda are dedicated to her. In later Tantric texts she occupies an important position. She is associated with Ushas, Indra, Rta, Satya in Rigveda, whereas in Atharvaveda she is associated with Surya. The Brahmanas and the Sutra literature often mention Ratri.
