According to Baba, what are the primary obstacles preventing a person from realizing the soul's true knowledge?

In Chapter 50, Baba identifies Desire and Anger as the main obstacles that obscure the soul's knowledge. They are described as immensely powerful forces that can "drown without water" and "burn without fire," capable of defeating even a wise person. These two reside within the senses, intellect, and mind. Through these faculties, Desire and Anger cover the soul's innate knowledge and cast a powerful delusion over it. The text uses the analogy that just as one must destroy a snake guarding a sandalwood tree, one must overcome Desire and Anger to attain the treasure of true knowledge.
