Sabdapurvayoga is atmavichara
Sabdapurvayoga is the return to that state prior to the arising of the ego. The Grammarian Bhartrhari’s method for attaining the Self involves tracing the mind back to its source. At that point the unreality of the ego is discovered. This is the true purification of the word. When Brahman is known to be all there is, there can no longer be any misunderstanding.
Bhartrhari has stated that Grammar is the straight road for those who would attain liberation in Brahman. The twentieth century Sage of Arunåcala, Ramana Maharshi, similarly referred to the discipline of åtmavicåra as the straight path to Self-realisation. The essence of Bhartrhari’s method is åtmavicåra. Sabdapurvayoga is atmavichara.
