How did the devotional practices like worship and Aarti around Sai Baba develop, and who were the key figures, besides Baba himself, in establishing these traditions?

The development of devotional practices was a gradual process involving several key devotees. Chapter 0 reveals that Maharaj was initially resistant to worship. Mhalasapati was the first to receive permission, and the practice was solidified after Nanasaheb Chandorkar's son was allowed to worship. Similarly, Maharaj did not initially permit Aarti, and the honor of performing the first one went to Tatyasaheb Noolkar. Radhakrishna-Aai was instrumental in starting the regular Shej-Aarti and Kakad-Aarti and organizing the broader community of devotees into various forms of service.
