What was the symbolic message Sai Baba gave to Das Ganu in a dream after his passing?

Following his Mahasamadhi, Sai Baba appeared in a dream to Das Ganu, who was in Pandharpur. As recounted in Chapter 42, Baba delivered a deeply symbolic message. He said, "The Mosque has collapsed; all the oilmen and grocers of Shirdi have troubled me too much. Therefore, I am leaving that place and have come here." The "collapsed Mosque" was a metaphor for his physical body, as the Dwarkamai mosque was his earthly home. The mention of being troubled by worldly people likely symbolized the endless troubles and petitions brought to him. He then asked Das Ganu to cover him with flowers and come to Shirdi, a request that prompted Das Ganu to rush there and perform Kirtan upon hearing the news of Baba's passing.
