According to Baba, what are the primary obstacles that prevent a person from realizing true knowledge?

As explained in Chapter 50, the primary obstacles to realizing true knowledge are Desire and Anger. These are described as being like coils of black cobras at the root of a sandalwood tree, creating a sheath over the womb of knowledge. They are so powerful that they can 'drown without water' and 'burn without fire,' defeating even a wise person. The text states that the senses, intellect, and mind are the abode of Desire, and through these, it covers the soul's knowledge and casts a powerful delusion over it, preventing one from attaining the treasure of self-knowledge.
