The text suggests Sai Baba didn't 'die' in the way we understand it. How does it describe his act of leaving the physical body?

The account in Chapter 43 reframes Sai Baba's departure as a voluntary and yogic act rather than a conventional death. It states that Sai Samarth possessed the ability to die at will and that he "burned the body in the fire of Yoga." This was not an end but a transition where he "merged himself into the unmanifest" to attain his previous, formless state. The text emphasizes that he remained present in the hearts of his devotees. This act is portrayed as a conscious choice to transcend the material state, not a passive submission to bodily decay, which is why the author notes that the mind cannot accept the simple talk of him having perished.
