What was the spiritual lesson behind Maharaj's continuous demands for Dakshina from Kashiram, even after he went broke?

The spiritual lesson was a profound one about overcoming pride and ego. As Chapter 0 explains, Kashiram's identity had become attached to being a giver, leading to pride, which is a significant barrier on the spiritual path. Maharaj's constant demands for Dakshina were not about the money itself but were a divine play, or leela, to dismantle this ego. By pushing Kashiram to the point of having to borrow and then being unable to borrow further, Maharaj made him confront his powerlessness. This experience was crucial for Kashiram to understand that the ability to give is not one's own but a divine grace. The entire episode was a form of spiritual surgery to purify the devotee's heart.
