According to Chapter 50, what is the relationship between Desire and Anger, and how do they impact the path to liberation?

Chapter 50 explains a direct causal relationship between Desire (Kama) and Anger (Krodha). Desire is presented as the root cause of all activity and disasters. The text explicitly states that when there is an obstruction to the movement of Desire, that very Desire transforms into the form of Anger. These two are described as powerful tendencies that are fundamentally against liberation and act as significant hinderers of knowledge. They are said to be attached to the soul, dwelling right next to the Brahman-form, constantly posing a threat to one's spiritual progress. Therefore, overcoming the pull of Desire is critical, as its frustration inevitably leads to Anger.
