How does Chapter 18 describe the God-devoted Tukaram's visit to Shirdi to meet Sai Baba?

The provided text from Chapter 18 does not describe a visit by the God-devoted Tukaram to Shirdi, nor any meeting with Sai Baba. Tukaram is mentioned once, but only in a metaphorical sense to praise a sacred book. Chapter 18 uses his devotion as a benchmark, stating that the sweetness of the book is like that which caused Tukaram to perform a thousand readings on Bhamchandra hill. This reference serves to highlight the spiritual potency of the text Baba recommended, not to document a historical event involving Tukaram and Baba.
