Can you provide an example from the text of a devotee who conquered lethargy and the need for rest through their devotion to Maharaj?

Yes, Nanasaheb Nimonkar is a prime example of a devotee who conquered lethargy through his service to Maharaj. As recounted in Chapter 0, even though he was over sixty years old, a time when one might naturally desire more rest, "laziness or a desire for rest never touched him while serving Maharaj." He dedicated the last three years of his life to constant and prompt service, only returning home for his daily rituals. This illustrates a profound spiritual principle: when service is performed with deep faith and love, it generates its own energy, making worldly fatigue and laziness irrelevant.
