What is the story of Mrs. Gokhale's devotion and her offering of khichdi to Sai Baba?

The story recounts a lady who had made a vow to offer khichdi, or naivedya, to Sai Baba. She traveled from Akola to Shirdi, but for fourteen days, the offering remained unmade. As detailed in Chapter 28, on the fifteenth day, her resolve strengthened, and she arrived with the khichdi at noon. She found that Baba was already having his meal behind a curtain. Driven by her enthusiasm, she did not wait, but moved the curtain with her own hand and entered. Baba reacted with a wonderous delight, taking the plate with both hands and eagerly eating the khichdi, which amazed all the devotees present.
