Based on the events in Chapter 19, what did Sai Baba teach about meditation and attaining true knowledge?

Following the narration of a story, Sai Baba imparted wisdom on spiritual practice. As explained in Chapter 19, he stated that true knowledge of the Soul requires meditation (Dhyana), which he described as the practice of the Self that brings peace to the mind. His core instruction was to become free from all desires and to meditate on the one who resides in all beings. Baba assured that if meditation is orderly, that which is to be attained—the true knowledge of the Soul—will surely be attained, and he equated his own form with pure knowledge.
