How does the text describe the progressive stages of spiritual transformation for a devotee who engages with Sai Baba's life story?

The text outlines a clear, multi-stage process for spiritual transformation. According to Chapter 3, the journey begins with the simple act of listening to Sai Baba's stories with respect, which is said to cure diseases. This is followed by a deeper intellectual engagement: to "contemplate them fully." The next stage moves from intellect to practice with "deep meditation (Nididhyasana)," which is said to bring peace. The culmination of this process is a profound shift in consciousness where the ego, represented by the thought 'I am That' (Aham-Soham), dissolves. This leads to a transcendent state of mind (Unman), where the devotee's heart becomes a "cloud of consciousness (Chaitanyaghan)," achieved through exclusive and complete faith.
