Srimad Bhagavad Gita -Ramanujacharya
Chapter-18 Mokṣa Sannyāsa Yogaḥ
Both renunciation and relinquishment as means for Liberation are enjoined in the Scriptures. Arjuna wants to know whether Tyāga and Sannyāsa are synonymous or not. “Do these two terms Sannyāsa and Tyāga have different meanings or do they signify the same thing? If they signify different things, I want to know their characteristics. If they are synonymous, their identical nature should be explained”.
