How does Chapter 33 connect the giving of Udi to the philosophical concepts of Maya and Brahman?

Chapter 33 of the Sai Satcharitra draws a direct and deep connection between the simple act of giving Udi and the profound philosophical concepts of Maya and Brahman. The chapter explicitly states that the Udi is a symbol demonstrating that the entire visible universe is ultimately insubstantial, like ash. It serves as a tangible reminder that "the entire universe is pervaded by Maya (illusion); Brahman alone is real." By accepting the Udi, devotees were encouraged to internalize this truth and maintain awareness of life's impermanence. The ash signifies the transient nature of the physical body and the world, urging the seeker to look beyond the illusion towards the eternal, unchanging reality of Brahman.
