What was the 'disciplined practice' mentioned in the text that one must follow to attain their desires, and who started it?

The phrase 'disciplined practice' is mentioned in Chapter 35 in the context of a specific gentleman's personal devotion after he was cured of bad dreams. His practice involved keeping a packet of Udi under his pillow, remembering Sai constantly, installing a picture of Baba, and worshipping it daily with a special offering of a garland on Thursdays. The text presents this as his personal routine that led to the attainment of his long-standing desire for peaceful sleep. It is not described as a formal, universally prescribed doctrine started by anyone in particular, but rather as an example of an individual's dedicated and heartfelt worship that yielded positive results.
