The source mentions that Udi has both spiritual and worldly benefits. Can you elaborate on this dual purpose?

Indeed, the Udi serves a dual role. While its primary purpose is spiritual, Chapter 33 explains that Sai is the 'helmsman of the path of spiritual welfare' who 'gives spiritual welfare while fulfilling worldly interests.' This suggests that the Udi aids in both spiritual growth and worldly matters. The text explicitly states that the greatness of Udi is increased by this quality and that there are 'countless' stories of its benefits for devotees' worldly interests, even though they are only told in condensed form within the book. Thus, it acts as a medium for both spiritual guidance and material well-being.
