From Sai Baba's perspective, why was it important for devotees to remember that their bodies would one day become ash?

According to the teachings described in Chapter 33, Sai Baba emphasized the impermanence of the physical body to foster spiritual wisdom and detachment. He explained that the body is like "wood made of five elements," which exists only to experience its destined enjoyments and will ultimately become ash. By giving Udi, he imparted a constant reminder of this truth, stating, "Such is the state of yours and mine; may you maintain this remembrance." This practice was not meant to be morbid but to help devotees rise above attachments to the physical form and the distinctions of the worldly realm, encouraging them to focus on the eternal truth that Brahman is the only reality.
