How does Chapter 50 explain the nature of Maya and its relationship to bondage and liberation?

In Chapter 50, Maya is portrayed as the supreme, indescribable illusion of name and form, which is very difficult to overcome. Its dwelling place is said to be any "pulse of imagination," and it is from this imagination that the states of both bondage and liberation are born. The text asserts the Vedic principle that liberation comes only from knowledge. However, it qualifies this by stating that the dawn of such knowledge is impossible without the destruction of sinful karma. Ultimately, a person who attains pure knowledge is said to have abandoned Maya by resolve, freeing them from its bondage.
