The provided text mentions a 'transformation of the mosque'. What specific changes occurred and when did this new phase begin?

The excerpts from Chapter 5 indicate that a significant shift, described as an "entirely new phase," began in the year 1912. This period marked the "real beginning of the transformation of the mosque." One of the most notable physical changes mentioned was the flooring. The ground of the mosque previously had knee-deep holes, making it uneven and difficult. Through the devotion of his followers, the flooring was paved with stones in a single night. This act not only improved the physical space but also signified the growing collective devotion and unity of the people gathering around Sai Baba.
