How does the practice of group reading, or Parayan, help foster a sense of community among Sai's followers?

The text explains in Chapter 0 that when a devotee studies or performs a Parayan of a detailed Guru biography, they are performing a form of Guru service. When other devotees join in these study sessions and Parayans, the act expands into a form of public service, described as serving God in humanity (Jan-Janardan). This collective spiritual practice allows devotees to connect with each other, share in the grace of the Guru, and collectively work towards achieving the purpose of their lives, forming a strong communal bond.
