Is there an example in the text of a devotee who demonstrated exceptional energy and a lack of laziness due to their connection with Maharaj?

Yes, the introduction in Chapter 0 presents the compelling case of Nanasaheb Nimonkar. He was an Honorary Magistrate who, in his later years, became an ardent devotee of Maharaj. The text highlights his remarkable dedication, stating that despite being over sixty, "laziness or a desire for rest never touched him while serving Maharaj." He spent the majority of his time, outside of brief daily rituals, in prompt service to Maharaj. This account from Chapter 0 serves as a powerful illustration of how a deep connection and selfless service to a spiritual guide can inspire extraordinary energy and completely overcome any tendency towards idleness or fatigue.
