Can you outline the various physical and mental acts of devotion to Sai Baba mentioned in the text?

Chapter 49 provides a comprehensive guide to expressing devotion to Sai Baba through various actions. Mentally and vocally, one should engage in the repetition of Shri Sai's name, contemplate His words in the heart, and meditate on His form in the mind. Physically, devotees are encouraged to circumambulate Sai with their feet, listen to the Satcharita with their ears, prostrate with their whole body, place their head at His feet, and use their sense of smell for the Nirmalya (sacred offerings). The text suggests that engaging in these purifying actions is the supreme means to break the bonds of worldly existence.
