In 1987 while visiting USA, Param Pujya Dadashri's health was rapidly deteriorating. He made a special request for Pujya Deepakbhai to come to the US. For forty-five days, Param Pujya Dadashri groomed him, constantly testing his knowledge of the Science. Finally, satisfied with his spiritual state, Param Pujya Dadashri performed a vidhi empowering him with special spiritual powers (siddhis) to conduct satsangs. Param Pujya Dadashri entrusted the task of grooming him for worldly tasks in the capable hands of Pujya Niruma.
Param Pujya Dadashri passed away in January 1988, knowing that his mission would continue through Pujya Niruma and Pujya Deepakbhai, as they had promised to fulfill his dream of world's salvation.
Pujya Deepakbhai continued to support Pujya Niruma with dedication and utmost devotion as she took over his grooming. They travelled throughout the world conducting satsangs / Gnan Vidhis and enlightened thousands of seekers. They worked tirelessly, compiling books on various topics based on Param Pujya Dadashri's recorded satsangs.
