How is Sai Baba's divine nature described in the provided text?

The text describes Sai Baba as a divine figure whose actions are a "play of this God." According to Chapter 18, His Leelas, or divine plays, are considered "unfathomable" and "incomprehensible." It is said that "He plays the play and remains separate," indicating a transcendent nature that is not fully enmeshed in the activities He orchestrates. Furthermore, His doings are described as being "not of human nature," which highlights His divine status beyond ordinary human understanding. Madhavrao emphasizes this by stating that only Baba Himself truly knows His own art and actions.
