Can you describe what Cholkar did to fulfill his vow once he finally reached Shirdi?

When Cholkar's long-awaited journey to Shirdi concluded, he immediately sought Sai Baba's darshan. The moment he saw Baba, he was filled with supreme bliss and prostrated himself at Baba's feet. To formally complete the vow he had made, Chapter 15 states that Cholkar, with a pure heart, distributed sugar and offered a coconut. Upon doing so, he expressed his joy, saying, "Today all my desires have been fulfilled." After this, he felt happy through conversation with Baba and then went to stay at the home of Mr. Jog, who was his host.
