According to Sai Baba's discourse in the provided text, what is the relationship between understanding the Self and the cessation of desire?

The text from Chapter 3 details Sai Baba's teaching on how self-realization extinguishes desire. He explained that desires originate in the intellect and have no connection to the Soul. Since Sai Maharaj is the form of the Soul itself, there is no impulse for desire within Him. When one understands the essence of 'Who am I?' and grasps the truth that the Self is all-pervading, the concepts of 'I' and 'mine' dissolve. For such a person, nothing remains to be desired, and various desires "dissolve like hail heated by the rays of the sun."
