Can you explain the deeper spiritual meaning behind Sai Baba giving Udi?

The spiritual significance of Udi is profound, serving as a powerful reminder of life's impermanence. Chapter 33 teaches that this worldly life is itself like Udi and that the gift of Udi helps one remember that our perishable bodies will one day fall, just like water on a lotus leaf. This realization is meant to encourage the renunciation of pride. The text further explains that the world is like a 'game of Rangoli made of ash,' and by contemplating this, one can realize the falsity of the world and find truth in Udi, which represents the ultimate destination of all name and form.
