Can you explain the deeper, philosophical meaning of the Udi given by Sai Baba?

The Udi given by Sai Baba carries a profound philosophical message about the nature of existence. Chapter 33 teaches that this worldly life is like Udi and that our perishable bodies will one day fall, just like water on a lotus leaf. The gift of Udi serves as a powerful reminder to renounce pride in the physical body. It encourages one to contemplate the falsity of the world, which is compared to a game of Rangoli made of ash, and to realize the ultimate truth through the symbolism of Udi, which represents the earth to which all forms return.
