What are some practical devotional activities a group of Sai followers can undertake together, based on the traditions mentioned in the Satcharita's preface?

Based on the information provided in Chapter 0, a highly recommended group activity is to perform a Parayan or Saptah of a detailed biography. The preface specifically identifies the Shri Sai Satcharita by Annasaheb Dabholkar as the ideal work for this purpose concerning Sai Baba. This practice is framed not just as personal study but as a communal act. By studying and performing Parayans together, devotees engage in a form of public service and service to God in humanity (Jan-Janardan), which fosters a strong community bond and helps each participant achieve the purpose of their lives.
