Can you explain the story behind Das Ganu's simple attire during his kirtan performance in Thane?

The story of Das Ganu's simple attire is a key event described in Chapter 15. While performing a kirtan near the Kaupineshwar temple in Thane, Das Ganu was noted for wearing only a simple pair of cloths (pancha), with a bare torso and no turban. This simple dress was a direct result of an earlier interaction with Sai Baba in Shirdi. On a previous occasion, when Das Ganu was dressed elaborately in a tunic, shoulder cloth, and turban for a kirtan, Baba questioned the necessity of such formal wear, asking, "Why the tunic, the shoulder cloth, and the turban?" This guidance from Baba led Das Ganu to adopt a simpler, unadorned style for his devotional performances.
