What was the significance of the Chavadi in Sai Baba's routine, and when did the celebrations there begin?

The Chavadi was a key location in Sai Baba's life, as he would sleep there every other day by rule. As Chapter 37 explains, this routine of alternating one night in the Masjid with the next spent at the Chavadi continued without interruption until His Samadhi. The celebrations at the Chavadi, which included worship, bhajan, and adoration, officially began on December 10, 1910. This established a significant new tradition for the devotees who gathered there for these special nights.
