Did Sai Baba require specific types of worship, or was he flexible in how devotees approached him?

Sai Baba demonstrated remarkable flexibility and did not require any specific type of worship. As Chapter 11 explicitly states, though he was changeless, he 'accepted worship and rituals; according to the devotee’s intent, he accepted all types.' This adaptability is shown through the wide variety of devotional acts his followers performed. Some would wash his feet, others would apply perfumes, and some would offer food. Chapter 11 even notes that some would apply horizontal sandalwood marks with two fingers, while others would worship him as a Shiva Lingam, showing he embraced the unique devotional inclinations of each person.
