Are there examples in the Satcharitra of devotees undertaking extreme physical hardship for the sake of worshipping Baba?

Yes, the account of Megha in Chapter 28 provides a clear example of a devotee undertaking significant physical hardship out of love for Baba. To fulfill his desire for worship, Megha would walk one and a half kos (about 4.5 km) and climb hills just to obtain bilva leaves. In another instance, on Makar Sankranti, Megha decided to give Baba an oil bath with water from the Godavari. As Chapter 28 recounts, after receiving Baba's permission, he set out with firm determination to travel eight kos, which is about 24 kilometers, to fetch the water and return. The text explicitly states that the thought of the hardship "did not even enter his dreams," highlighting his immense enthusiasm.
