What did Baba teach is the ultimate way to get rid of all desires and find the 'eternal treasure' he mentioned?

Sai Baba outlined a profound spiritual path to transcend desire and find an 'eternal treasure.' The journey, as described in Chapter 3, begins with performing his service with devotion. However, this service evolves into a deeper understanding of his true nature. Baba clarified that his physical body is perishable, and true worship is of the imperishable Brahman, which is his real self. The key is to realize his omnipresence—that he is the 'eightfold nature' filling the entire universe. By internalizing this truth and contemplating 'Who am I,' the devotee's sense of 'I' and 'mine' dissolves. Chapter 3 explains that desires, which belong to the intellect, then 'dissolve like hail heated by the rays of the sun,' revealing the eternal treasure of self-realization and peace.
