How does Sai Baba describe his omnipresence and the path to achieving oneness with him?

Sai Baba explains his omnipresence by declaring, "The nature of the inner Guru appears in all beings; there is no empty spot without me." As detailed in Chapter 44, he guides devotees that by practicing this realization, his omnipresence will be experienced, leading to harmony and complete oneness with him. This chapter further explains that focusing on the consciousness-form purifies the inner heart, a process Baba likens to a spiritual "bath in the Ganges for you, without touching the water of the Ganges," signifying a deep internal cleansing through devotion.
