Based on Baba's discourse in 1916, what is the relationship between understanding 'Who am I?' and the cessation of desires?

According to the teachings found in Chapter 3, Sai Baba explains that desires originate in the intellect and have no connection to the Soul, which he embodies. He equates his true form with the Soul itself, which is devoid of the impulse for desire. The key to overcoming desire is to understand the answer to the question, "Who am I?" When one realizes their true nature is the Self—which is omnipresent and one with everything—the very foundation of desire crumbles. Baba illustrates this by saying that when this essence is understood, various desires "dissolve like hail heated by the rays of the sun," as there is nothing external to the Self to be desired.
