What is the distinction between 'Jnana' and 'Avidya' as outlined in the provided text?

The text draws a clear distinction between knowledge ('Jnana') and ignorance ('Avidya'). As detailed in Chapter 50, 'Jnana' is the profound realization that "I am the Soul, the pure witness; purely enlightened and liberated," and understanding that "This Soul is Brahman." It is the eternal pulse of 'I am Brahman.' In stark contrast, 'Avidya' is described as the attitude of being "a sinner, unfortunate, luckless." This negative self-perception is considered the very source or "mine of 'Avidya'." The text further explains that from these two ancient powers of Maya, one leads to bondage while the other leads to liberation.
