According to the text, what is the true nature of liberation (Moksha) and how can it be attained?

The provided text explains that liberation, or Moksha, is not an external achievement but rather the state of 'abiding in one's own form.' As described in Chapter 50, this is the only true liberation. The path to attaining this state is through knowledge, specifically the realization of the unity between Brahman and the Soul. When this profound knowledge occurs, it leads to the removal of ignorance (Avidya) and the dissolution of the causal body, which is the root of worldly illusion. Therefore, Moksha is achieved by dispelling ignorance with the light of self-knowledge, allowing one to rest in their inherent, true nature.
