What does it mean that Sai Baba was 'devoid of bodily impulses' and could 'die at will'?

The statement that Sai Baba was 'devoid of bodily impulses' and could 'die at will' highlights his complete mastery over the physical form and his identity as the Supreme Brahman. As explained in Chapter 43, the body is considered 'merely an adjunct' for such a being. He was not subject to its limitations or compulsions, including physical or mental illness, which are attributed to past karma from which he was free. The ability to 'die at will' signifies his status as a master Yogi who controlled his life force completely. Instead of succumbing to death, he chose the moment and method of his departure, using the 'fire of Yoga' to consciously merge his consciousness back into the unmanifest, universal state. This demonstrates that his life and death were not governed by ordinary biological processes but were a part of his divine play for the salvation of devotees.
