The text says Sai Baba appeared 'for the sake of the devotees’ protection.' How does his departure relate to this purpose?

According to Chapter 43, Sai Baba's entire incarnation was driven by a 'sole desire for the welfare of devotees.' He appeared in Shirdi, drawn by their past merits, specifically for their protection. The text suggests that once this 'task for the devotees is over,' he chose to leave his physical form. However, his departure was not an end to his protection. By merging into the unmanifest, he transcended the limitations of a physical body and stayed in the hearts of his devotees. In this state, he 'always keeps the devotees awake' and fills the entire world, continuing his protective influence in a more universal and eternal manner.
