Can you explain the relationship between Desire and Anger as described in the source?

Chapter 50 provides a clear and direct explanation of the connection between Desire (Kama) and Anger. It states that Desire is the fundamental cause of all disasters and activities that lead one astray. Anger is not a separate force but is actually a transformation of Desire itself. The text specifies that 'When there is an obstruction to the movement of Desire, only then does that Desire become Anger.' This means that anger arises as a direct consequence of a frustrated or thwarted desire. Both are considered significant hindrances to liberation and the attainment of knowledge, dwelling right beside the soul and working against spiritual progress.
