What was Sai Baba's true intention behind asking for Dakshina from his devotees?

According to the provided texts, Sai Baba's primary intention in accepting Dakshina was the spiritual purification of his followers. Chapter 14 explains that many who came to him were deeply attached to worldly desires, seeking material gains like wealth and power. Baba's profound method involved using the act of giving Dakshina to cleanse their hearts of these attachments. It is noted that through this process, even those who initially came to mock him would have their negative intellect burned away, leading them to become devoted. The ultimate aim was to guide devotees to use wealth for religious merit, which in turn fosters knowledge and transforms self-interest into the highest spiritual goal.
