The text mentions that some beings 'incarnate by their own will' for the 'welfare of devotees.' How does this relate to the concepts of birth and death for them?

Chapter 43 clarifies that for beings who incarnate by their own will with the sole desire for the welfare of devotees, the conventional rules of birth and death do not apply. These events are described as 'false imaginations' in their case. The text explains that death is attached to birth, but these beings, who can 'place their feet on the head of Time,' are not touched by this cycle. Sai Baba is presented as such an avatar, who appeared in Shirdi due to the merits of his devotees. His life and departure were a 'spontaneous play of Yoga' for their salvation, not a submission to the natural laws of birth and death.
