Chapter 29 of the Shri Sai Satcharita paints a rich portrait of Sai Baba's character. He is described first and foremost as a great saint who was patient, generous, and self-controlled. His compassion extended to all, especially pilgrims, the poor, and the destitute, and he was known to inquire about their needs. The chapter highlights his 'abundant generosity' in distributing money daily. Furthermore, it reveals his deep affection for children, as seen in his tender interactions with the little girl Amani.
