The source text mentions that even 'great knowers' can fall into ruin. How does this happen, and what does it reveal about the power of desire?

Chapter 50 provides a sobering account of how even wise individuals can be led to their downfall. It explains that their intellect can become corrupted, causing them to behave according to their whims despite knowing the correct path. This can happen through the influence of bad company, leading them to do exactly what should not be done. The core issue identified in Chapter 50 is Desire (Kama), which is the fundamental cause of all activity and overrides one's knowledge of right and wrong. Even if a wise person knows that committing a sin is an act of ignorance, Desire compels them to act, much like a moth is drawn to a flame. This illustrates the powerful and insidious nature of Desire as the ultimate cause of all disasters and a hinderer of knowledge.
