Why did Cholkar have to postpone his trip to Shirdi, and what personal commitment did he uphold during that time?

Cholkar postponed his trip to Shirdi due to financial constraints. Chapter 15 describes him as coming from a "poor household" and notes that for a worldly man, the "'threshold-ghat' (home expenses) is very difficult to cross." This implies he simply could not afford the journey after passing his exam. Despite this delay, Cholkar remained steadfast in his devotion. As a personal penance and a way to honor his unfulfilled vow, he completely gave up sugar, which he treated as an "inedible substance." He even drank his tea without sugar until he could finally make the journey to Shirdi and present his offering to Sai Baba.
