What is the deeper philosophical meaning behind Sai Baba giving Udi to his devotees, as explained in Chapter 33?

Chapter 33 delves into the profound philosophical message Sai Baba conveyed through the act of giving Udi. The practice was a form of spiritual instruction. The chapter explains that the Udi, or Vibhuti, symbolizes the transient nature of the entire visible universe, reminding us that it is all ultimately like ash. Baba taught that the physical body, composed of five elements, is temporary and will also become ash once its destined enjoyments are exhausted. By giving the Udi, he encouraged devotees to maintain this awareness and detachment from worldly illusion (Maya). The ultimate teaching conveyed, as stated in this chapter, is that Brahman alone is the ultimate reality.
