Describe Sai Baba's reaction to the khichdi offering and what it revealed to the other devotees.

When the lady pushed past the curtain and offered the khichdi, Sai Baba's reaction was described as a wonder. According to Chapter 28, he acted as if he was incredibly hungry for that specific dish, holding the plate with both hands. He became delighted upon seeing the khichdi and began lifting morsels into his own mouth with great eagerness. This display of enthusiasm from Baba filled everyone's minds with amazement. Hearing the backstory of the vow and the delay, the onlookers felt the uniqueness of Sai, who so clearly valued and rewarded the devotee's persistent love.
