Śruti (Sanskritश्रुति, "heard") describes the central canon of Hindusacred texts, dating from across the entire history of Hinduism beginning with the some of the earliest known Hindu texts and ending in the early modern period with the later Upanishads. The term is used in opposition to Smrti, or "remembered" - these latter being based upon tradition, whereas Śruti are considered revealed records of the "cosmic sound of truth" heard by rishis (saints or sages).
Pre-eminent in sruti literature are the four Vedas:
Atharva-Veda (a collection of ancient spells and charms)
The liturgical core of each of these was supplemented by commentaries, the Brahmanas and later the Aranyakas and Upanishads, which all likewise belong to the śruti canon. The literature of the shakhas or schools further amplified the material associated with each of the four core traditions.[1]
"In no country, I believe, has the theory of revelation been so minutely elaborated as in India. The name for revelation in Sanskrit is Sruti, which means hearing; and this title distinguished the Vedic hymns and, at a later time, the Brahmanas also, from all other works, which however sacred and authoritative to the Hindu mind, are admitted to have been composed by human authors. The Laws of Manu, for instance, are not revelation; they are not Sruti, but only Smriti, which means recollection of tradition. If these laws or any other work of authority can be proved on any point to be at variance with a single passage of the Veda, their authority is at once overruled. According to the orthodox views of Indian theologians, not a single line of the Veda was the work of human authors. The whole Veda is in some way or the other the work of the Deity; and even those who saw it were not supposed to be ordinary mortals, but beings raised above the level of common humanity, and less liable therefore to error in the reception of revealed truth. The views entertained by the orthodox theologians of India are far more minute and elaborate than those of the most extreme advocates of verbal inspiration in Europe. The human element, called paurusheyatva in Sanskrit, is driven out of every corner or hiding place, and as the Veda is held to have existed in the mind of the Deity before the beginning of time..."[3]
