Can you explain the difference between 'Vidya' and 'Avidya' as described in the Satcharita?

Chapter 50 provides a deep philosophical distinction between 'Vidya' (knowledge) and 'Avidya' (ignorance). 'Vidya' is described as the pure, eternal pulse of realizing "I am Brahman." It is the inner consciousness of being the pure, enlightened, and liberated Soul, immovable in non-dual bliss. Conversely, 'Avidya' is characterized as the attitude of seeing oneself as a "sinner, unfortunate, luckless." These two are presented as ancient powers of Maya, where 'Vidya' leads to liberation from bondage, while 'Avidya' is the very source of that bondage for the soul.
