According to Sai's teachings, what is the fundamental way to overcome the fear of death?

Chapter 37 explains that death itself is the great fear of worldly existence. The primary method to become fearless from it is to hold firmly to the Guru’s pair of feet. The Guru will grant the non-dual intellect, which is key to liberation. When one surrenders completely to the Satguru with body, speech, and mind, there is no longer any reason to talk about the fear of worldly existence. The text poses the question of why one should worry about the world when the Guru is the one who removes everything, including the very ignorance that causes fear.
