What does the text identify as the fundamental source of bondage and liberation?

The source text from Chapter 50 identifies the origins of both bondage and liberation within the powers of Maya and the nature of one's own consciousness. It explains that there are two ancient powers: from one comes the state of bondage, and from the second comes liberation. Bondage arises from 'Avidya' (ignorance), which is characterized by the attitude of being "a sinner, unfortunate, luckless." In contrast, liberation arises from 'Vidya' (knowledge), which is the pure realization that "I am the Soul" and "I am Brahman." The text further clarifies that the very birth of these states comes from imagination, which is the domain of Maya.
