What was the underlying reason for Sai Baba's shift in behavior regarding Dakshina specifically with Kashiram?

According to Chapter 0, Maharaj did not typically accept Dakshina during that period, but he would take a small amount from Kashiram. This led Kashiram to develop an attachment and pride, feeling bad on days his offering wasn't taken. Seeing this pride as an obstacle to Kashiram's spiritual progress, Maharaj initiated a leela. He began a "barrage of demanding Dakshina," pushing Kashiram into financial hardship. The entire purpose of this divine play was to completely remove the pride associated with giving from Kashiram's heart, teaching him a profound lesson about ego and surrender.
