What does it mean to surrender to Sai, and what is the reward for living by His words?

Surrendering to Sai involves a deep, internal commitment. As Chapter 19 clarifies, it's not a passive state. A devotee is expected to put in the effort, symbolized by the instruction to 'do the exercises (Zor)'. The surrender comes in trusting the Guru completely for the results and sustenance, as Sai promises to 'stand behind you with a bowl'. A devotee should surrender with an undivided heart and then witness the wonders of devotion and the marvels of Sai's skill. The text makes a powerful promise for those who live by treating Baba's words as authoritative: they are assured to have 'reached the mine of happiness in this world and the next.' This complete trust and adherence to the Guru's guidance is the path to ultimate contentment.
