What different kinds of devotional activities did Sai Baba assign to his followers, and how did the author's task fit into this?

According to Chapter 3, Sai Baba was a 'generous giver' who engaged his followers in various forms of service tailored to them. He had some devotees build temples and monasteries, while others were engaged in the joy of kirtan (devotional singing). He even sent some on pilgrimages. The author contrasts these paths with his own, stating, 'me, He sat down to write.' While other devotees pursued paths like building river-ghats, the author recognized his specific duty and resolved to 'take the straight path: the study of Sai’s life story,' dedicating himself fully to the task Baba had assigned him.
