According to the text, what different forms of selfless service did devotees like Balaji Patil and Radhakrishnabai perform for Sai Baba?

Chapter 35 details several acts of selfless service. Balaji Patil Nevasakar, a great devotee, wore out his body for Baba by performing the daily task of sweeping the paths Baba used to walk. In a profound act of self-sacrifice, he would also bring his entire harvest to the mosque, offering it at Baba's feet and only taking home what Baba gave back. Radhakrishnabai, a Brahmin woman, also demonstrated great devotion by waking early to sweep and clean Baba's paths, a service considered menial, which never troubled her faultless heart. Later, Abdul also took up this service, showing how different devotees expressed their love and dedication.
