Śaṅkarācārya's commentary

"Saṃnyāsa": the connotation of the term. "Tyāga": the connotation of the term. "Severally": as distinguished from each other. Keśin was an Asura whom the Lord slew, and the Lord is therefore addressed as 'Keśi-niṣūdana,' the Slayer of Keśin. The words have been used here and there in the preceding discourses, their connotations however not being clearly distinguished.
