I feel lost and spiritually stuck since Sai Baba is no longer physically present. How can I understand his continued existence and overcome this feeling?

It's natural to feel this way, but the teachings in Chapter 43 offer profound reassurance. Sai Baba's physical departure is not an end but a transition. He is described as a Yogi who could die at will, choosing to merge his form into the unmanifest and reside forever in the hearts of his devotees. Chapter 43 explains that for a being like Sai, who is the complete Supreme Brahman, the concepts of birth and death are mere illusions. He has simply attained his previous unmanifest state, from where he continues to enjoy his true self and 'always keeps the devotees awake.' By merely remembering his name, the illusion of birth and death vanishes, confirming his eternal presence.
