What is the 'Unmanifest' body, and how is it connected to achieving Moksha or liberation?

The 'Unmanifest' (Avyakruta) is identified as the 'causal' (karana) body of the soul. According to Chapter 50, it is characterized as being with the reflection of consciousness and is the very cause of pure ignorance (Avidya). This ignorance forms a veil that obscures the true nature of the Soul. The text emphasizes that the removal of this causal body is essential for liberation, and this can only be accomplished through the profound knowledge of the unity between Brahman and the Soul. Attaining this knowledge dissolves the ignorance, allowing one to abide in their own true form. This state of 'abiding in one's own form' is precisely what is defined as Moksha, or liberation, and the text states there is no other path to it.
