Can you tell me about Sai Baba's strange sleeping habits as described in the Satcharitra?

Chapter 10 provides a fascinating account of Sai Baba's unusual sleeping arrangement. He would rest upon a narrow wooden plank, described as being merely four cubits long and one span (about nine inches) wide. This plank was not on the floor; instead, it was suspended from the rafters of the mosque, hung like a swing by pieces of old rags. Baba would sleep on this precarious perch with lamps kept burning at his head and feet. The text emphasizes that his movements were imperceptible, as no one ever saw him climb onto or descend from the plank, highlighting his extraordinary divine powers or Siddhis.
