What is the ultimate path to achieving Moksha, and what is the main obstacle that needs to be removed?

The ultimate path to Moksha, or liberation, is explicitly defined in Chapter 50 as 'abiding in one's own form.' The text asserts that there is no other liberation besides this. The primary obstacle to achieving this state is the 'causal body' of the soul, which is described as being made of pure ignorance (Avidya). The only way to remove this fundamental ignorance is to attain the 'knowledge of the unity of Brahman and the Soul.' When this realization occurs, ignorance is dispelled, allowing the soul to abide in its true nature, which is Moksha. Therefore, the discernment and removal of ignorance is the essential task.
