Based on the provided text, what is the primary lesson that the gift of Udi is meant to teach devotees about life?

The primary lesson imparted through the gift of Udi is the impermanence of worldly life and the need to renounce pride in our perishable bodies. Chapter 33 explicitly states, 'This worldly life is like Udi,' and encourages devotees to keep this remembrance in mind. The text further elaborates that our bodies will inevitably fall, 'like water on a lotus leaf,' and that the gift of Udi demonstrates this truth. It is a call to contemplate the falsity of the world, which is likened to a 'game of Rangoli made of ash,' and to instead realize the ultimate truth that the Udi itself represents.
