According to Chapter 50, what exactly is Moksha and what is the only way to achieve it?

In Chapter 50, Moksha, or liberation, is defined with great clarity as 'abiding in one's own form.' The text emphasizes its simplicity and directness by stating, 'Other than this, there is no other liberation.' It is not an external goal but an internal realization of one's true nature. The scripture is unequivocal that there is only one method to achieve this state: the removal of ignorance (Avidya). This removal happens exclusively through the attainment of the knowledge of the unity of Brahman and the Soul. When this unifying knowledge occurs, the causal body of ignorance is dissolved, and one naturally abides in their own form, which is Moksha.
