How does Chapter 20 reconcile Sai Baba's abstract, formless aspect with the tangible, physical experiences of his followers?

Chapter 20 presents a sophisticated view of Sai Baba's nature by bridging his abstract and physical manifestations. It explicitly states that "Sai is originally formless, but took form for the sake of his devotees." This concept is immediately followed by a very tangible description of the scene after the noon Aarti, where Baba physically distributes Udi and speaks to his followers. The chapter then addresses the passage of time by noting that while these physical interactions are in the past, they are not lost. It teaches that through the "power of firm meditation," a devotee can make these past celebrations visible again, effectively allowing one to experience the form of the formless Guru, thereby connecting the spiritual and physical realms.
