The principal schools of Vedānta are based on their interpretation of the Brahmasutras of Bādarāyaṇa. The pioneering ācāryas of these schools often try to garner support for their philosophy from the more ancient teachers who might have commented upon it. One such, quoted by Rāmānuja, is the Vṛttikāra Bodhāyana.
Śaṅkara refers to one Upavarsa. According to Vedānta Deśika both are the same person. Upavarsa had two other names, Kṛtakoṭi and Halabhuti. Nothing is known about him. According to some scholars he wrote a commentary on the Purvamimānsā Sutras and existed during the period 100 B.C. and A.D. 100.
