The text mentions that Baba 'left the body.' What does this actually mean and where did he go?

When chapter 43 states that Sai Baba 'left the body,' it does not imply a conventional death. Instead, it describes a voluntary act of a great Yogi. It explains that Sai Samarth could die at will and that he 'burned the body in the fire of Yoga.' Rather than perishing, he merged himself into his previous unmanifest state. The text emphasizes that he remains ever-present, having stayed in the hearts of his devotees. It posits that the one who was so firmly imprinted in the consciousness of devotees cannot truly be gone, and he continues to enjoy his true self while keeping his followers spiritually awake.
