According to the provided text, what are the recommended devotional practices for a group of devotees wanting to connect with their Guru?

The text outlines specific devotional practices centered on sacred literature. Chapter 0 recommends that devotees can perform Parayan or Saptah, which are dedicated, continuous readings of a holy book. It is noted that for this practice to be most effective, a detailed and comprehensive biography is required. While works by poets like Shri Dasganu Maharaj are mentioned, their sections on individual saints are considered too brief. The text promotes the study of extensive biographies, like the Shri Sai Satcharita, as a way for a congregation of devotees to receive service from the Sadguru and collectively achieve the purpose of their lives.
