What is meant by the 'spontaneous play of Yoga' and how does it relate to Sai Baba's death?

Chapter 43 describes a perfected Yogi's mastery over life and death as a 'spontaneous play of Yoga for the sake of the devotees' salvation.' This refers to actions like holding or releasing the breath at will or 'wandering in an invisible form.' In the context of Baba's passing, it means his death was not a passive event but a conscious, controlled act of yogic power. The text states he could 'die at will' and 'burned the body in the fire of Yoga,' indicating he chose the moment and method of his departure to merge with the unmanifest. This portrays his death not as a tragedy, but as a sublime yogic feat performed for a higher purpose.
