The text mentions Tukaram performed a thousand readings on Bhamchandra hill. What was Sai Baba's commentary on Tukaram's specific austerities?

While the provided text mentions the God-devoted Tukaram and his thousand readings of a sweet book on Bhamchandra hill, it does not record any specific commentary from Sai Baba about Tukaram's austerities. The reference to Tukaram in Chapter 18 is used to illustrate the profound sweetness and divine inspiration of the book Uddhava Gita, which Baba himself encouraged his devotees to read. The focus is on Baba's method of instruction, which involved reading divinely inspired books for spiritual attainment, not on analyzing the practices of other saints.
