How does the text define liberation, or Moksha, and what is it not?

Liberation, or Moksha, is defined very specifically in Chapter 50. It is described as 'abiding in one's own form.' This means that Moksha is not the attainment of something new or external, but rather the realization and stabilization in one's true, inherent nature. The text emphatically states, 'Other than this, there is no other liberation; abiding in one's own form is Moksha.' This state is achieved only when the knowledge of the unity of Brahman and the Soul arises, which in turn causes the removal of ignorance and the 'causal body.' It is the culmination of dispelling the illusion of a separate self and realizing the non-dual reality.
