According to the provided text, what is the path to liberation, or Moksha?

The path to liberation involves removing the veil of ignorance, which is the cause of the 'causal' body of the soul. Chapter 50 explains that true liberation, or Moksha, is simply 'abiding in one's own form.' This state is not something to be achieved externally, but rather realized internally. The text explicitly states that the removal of the causal body and the underlying ignorance happens only through the knowledge of the unity of Brahman and the Soul. Other than this, there is no other path to liberation.
