Transmission

The Vedas were orally transmitted since their composition in the Vedic period for several millennia. The authoritative transmission of the Vedas is by an oral tradition in a sampradaya from father to son or from teacher (guru) to student (shishya), believed to be initiated by the Vedic rishis who heard the primordial sounds. Only this tradition, embodied by a living teacher, can teach the correct pronunciation of the sounds and explain hidden meanings, in a way the "dead and entombed manuscript" cannot do. As Leela Prasad states, "According to Shankara, the "correct tradition" (sampradaya) has as much authority as the written Shastra," explaining that the tradition "bears the authority to clarify and provide direction in the application of knowledge."

The emphasis in this transmission is on the "proper articulation and pronunciation of the Vedic sounds", as prescribed in the Shiksha, the Vedanga (Vedic study) of sound as uttered in a Vedic recitation, mastering the texts "literally forward and backward in fully acoustic fashion." Houben and Rath note that the Vedic textual tradition cannot simply be characterized as oral, "since it also depends significantly on a memory culture." The Vedas were preserved with precision with the help of elaborate mnemonic techniques, such as memorizing the texts in eleven different modes of recitation (pathas), using the alphabet as a mnemotechnical device, "matching physical movements (such as nodding the head) with particular sounds and chanting in a group" and visualizing sounds by using mudras (hand signs). This provided an additional visual confirmation, and also an alternate means to check the reading integrity by the audience, in addition to the audible means. Houben and Rath note that a strong "memory culture" existed in ancient India when texts were transmitted orally, before the advent of writing in the early first millennium CE. According to Staal, criticising the Goody -Watt hypothesis "according to which literacy is more reliable than orality," this tradition of oral transmission "is closely related to Indian forms of science," and "by far the more remarkable" than the relatively recent tradition of written transmission.

While according to Mookerji, understanding the meaning (vedarthajnana or artha - bodha) of the words of the Vedas was part of the Vedic learning, Holdrege and other Indologists have noted that in the transmission of the Samhitas, the emphasis is on the phonology of the sounds (śabda) and not on the meaning (artha) of the mantras. Already at the end of the Vedic period their original meaning had become obscure for "ordinary people," and niruktas, etymological compendia, were developed to preserve and clarify the original meaning of many Sanskrit words. According to Staal, as referenced by Holdrege, though the mantras may have a discursive meaning, when the mantras are recited in the Vedic rituals "they are disengaged from their original context and are employed in ways that have little or nothing to do with their meaning." The words of the mantras are "themselves sacred," and "do not constitute linguistic utterances." Instead, as Klostermaier notes, in their application in Vedic rituals they become magical sounds, "means to an end." Holdrege notes that there are scarce commentaries on the meaning of the mantras, in contrast to the number of commentaries on the Brahmanas and Upanishads, but states that the lack of emphasis on the "discursive meaning does not necessarily imply that they are meaningless." In the Brahmanical perspective, the sounds have their own meaning, mantras are considered as "primordial rhythms of creation", preceding the forms to which they refer. By reciting them the cosmos is regenerated, "by enlivening and nourishing the forms of creation at their base. As long as the purity of the sounds is preserved, the recitation of the mantras will be efficacious, irrespective of whether their discursive meaning is understood by human beings." Frazier further notes that "later Vedic texts sought deeper understanding of the reasons the rituals worked," which indicates that the Brahmin communities considered study to be a "process of understanding."

A literary tradition is traceable in post-Vedic times, after the rise of Buddhism in the Maurya period, perhaps earliest in the Kanva recension of the Yajurveda about the 1st century BCE; however oral tradition of transmission remained active. Jack Goody has argued for an earlier literary tradition, concluding that the Vedas bear hallmarks of a literate culture along with oral transmission, but Goody's views have been strongly criticised by Falk, Lopez Jr,. and Staal, though they have also found some support.

The Vedas were written down only after 500 BCE, but only the orally transmitted texts are regarded as authoritative, given the emphasis on the exact pronunciation of the sounds. Witzel suggests that attempts to write down the Vedic texts towards the end of 1st millennium BCE were unsuccessful, resulting in smriti rules explicitly forbidding the writing down of the Vedas. Due to the ephemeral nature of the manuscript material (birch bark or palm leaves), surviving manuscripts rarely surpass an age of a few hundred years. The Sampurnanand Sanskrit University has a Rigveda manuscript from the 14th century; however, there are a number of older Veda manuscripts in Nepal that are dated from the 11th century onwards.
