According to Sai Baba's discourse, what is the fundamental way for a person to overcome worldly desires?

In the philosophical discourse recorded in Chapter 3, Sai Baba explains that the key to overcoming worldly desires is to understand one's true identity. He states that desires arise in the intellect, not the Soul, and Sai Maharaj is the form of the Soul itself, which has no impulse for desire. By meditating on the essence of 'Who am I' and realizing that the Self, or Brahman, is omnipresent and pervades everything, the attachment to 'I' and 'mine' dissolves. When this profound realization occurs, various desires are said to dissolve naturally, just as hailstones melt when heated by the sun's rays.
