Vedas - Vedanta

Vedanta

While contemporary traditions continued to maintain Vedic ritualism (Śrauta, Mimamsa), Vedanta renounced all ritualism and radically re-interpreted the notion of "Veda" in purely philosophical terms. The association of the three Vedas with the bhūr bhuvaḥ svaḥ mantra is found in the Aitareya Aranyaka: "Bhūḥ is the Rigveda, bhuvaḥ is the Yajurveda, svaḥ is the Samaveda" (1.3.2). The Upanishads reduce the "essence of the Vedas" further, to the syllable Aum (ॐ). Thus, the Katha Upanishad has:

"The goal, which all Vedas declare, which all austerities aim at, and which humans desire when they live a life of continence, I will tell you briefly it is Aum" (1.2.15)
