What is Baba's primary teaching on how to eliminate fear from one's life?

The primary teaching for eliminating fear, as detailed in Chapter 37, is to completely surrender to the Satguru. When you surrender with your body, speech, and mind, and merge your intellect to be entirely subordinate to the Guru, there is no room left for the fear of worldly existence. This chapter emphasizes that the greatest fear is death itself, and to become fearless from it, one must hold firmly to the Guru’s feet. He is the one who removes all worries and grants the non-dual intellect, which is the key to attaining a state where there is not even a trace of fear.
