What is the 'Unmanifest' and how can one be liberated from it?

According to the teachings in Chapter 50, the 'Unmanifest' (Avyakruta) is identified as the causal body of the soul, which is the source of pure ignorance (Avidya). This state is described as being neither with parts nor without parts. The text clarifies that liberation, or Moksha, is not a separate state to be achieved but is simply 'abiding in one's own form.' The only way to attain this liberation and remove the causal body of ignorance is through gaining the knowledge of the profound unity between Brahman and the individual Soul. There is no other path to Moksha besides this realization.
