Describe the promise Babasaheb Tarkhad made to his son and the instance where he failed to keep it.

Babasaheb Tarkhad made a solemn promise to his son to ensure the family's devotional practices continued uninterrupted. According to Chapter 9, he assured his son, "Go, I will offer Naivedya daily; be certain... Without first dedicating to Sai, no one will consume food." Tarkhad began performing the worship himself, offering a piece of sugar candy daily. However, the text recounts one day when, being preoccupied with his business at the mill, he completely forgot to make the offering. Everyone in the household finished their meals without the Naivedya being offered first, marking a break in his promise and his devotional rule.
