Did Sai Baba practice any form of yoga or deep meditation, especially in his final days?

The source text provides fascinating details about Sai Baba's spiritual practices. In the two weeks leading up to his passing, he engaged in a profound form of contemplative meditation by listening to the Ramayana with focused concentration for fourteen days and nights. As Chapter 44 explains, this period of intense focus concluded on the day of Vijayadashami when he attained the state of bodilessness. The text also alludes to a remarkable event from 32 years prior, where Baba drew his life force into the crown of his head for three full days, a practice reminiscent of advanced yogic states, which left observers unsure if it was a deep trance (Samadhi) or death.
