What happened on December 10th involving Dixit and Khaparde, and what other major event started on that same day?

On the tenth of December, a day after the Wada's foundation was completed, Sai Baba gave contrasting instructions to two of his devotees. As detailed in Chapter 4, Baba gave Dadasaheb Khaparde permission to return home, but he simultaneously ordered Kakasaheb Dixit to proceed with laying the foundation. This highlights the unique instructions Baba gave to different individuals. Chapter 4 also notes another great event that began on this very same day: the 'Shej-Aarti,' or night prayer, was initiated in the Chavadi with great devotion and love, making December 10th a doubly significant date in Shirdi's history.
