Bhagavad Gita – Gita Introduction
MOKSA: FREEDOM FROM WHAT?
Even though it comes last, moksa is a very important purusartha, as we shall see. Moksa is recognised as a pursuit only by a very few people in any given generation. Because a certain appreciation, a certain maturity or insight, about life and its struggles
is required to understand moksa, people do not discerningly pursue it, although everyone is in fact, always seeking freedom in one form or other.
