What is 'Moksha' or liberation, and what is the only path to achieve it according to this text?

As detailed in Chapter 50, Moksha, or liberation, is defined as 'abiding in one's own form.' The text is emphatic that there is no other form of liberation besides this. The singular path to achieving Moksha involves the removal of ignorance (Avidya). This ignorance is the cause of the 'causal body' or the 'Unmanifest.' Therefore, liberation is only possible when the knowledge of the unity of Brahman and the Soul is realized. This specific knowledge is the sole means to remove the veil of ignorance and, consequently, attain the state of Moksha by abiding in one's true nature.
