|The Shrimad Rajchandra Mandir is built around the same hallowed rock, seated on which Shrimadji had experienced the bliss of the Siddhatmas. He had thereupon said to the monks present there, "Listen, O Munis! This rock is indeed the Siddhashila, for today I have experienced the bliss of the Siddhatmas seated upon it. Never forget this place." Seated on this very rock, he had conducted discourses for hours on end on the 'Dravya Sangrah' - a supreme treatise on the soul and other substances that comprise the universe.
