After coming to Dervan-Savarde, he commenced service to Sadguru Shree Digambarbaba Wahalkar Maharaj in Datta Temple. In 1951, Shree Sant Digambarbaba Wahalkar Maharaj attained Mahasamadhi (last conscious communion with God). Shree Sant Sitarambuwa constructed the Samadhi-Mandir (Temple-shrine) of his Sadguru and a small Muth to stay.
More than 40 years passed like this. In order to that Shree Sant Sitarambuwa should not suffer hardship in his old age in pursuing his spiritual path and also enable young devotees to learn lessons from his totally dedicated life, Shree Vitthalrao Ganesh Joshi alias Shree Digambardas Maharaj established a Seva Mandal in Mumbai in 1958 which later served as stepping stone for the formation of Sant Sitarambuwa Charitable Trust after the Mahasamadhi (last conscious communion with God) of Shree Sant Sitarambuwa Maharaj on January 18, 1969. A decade ago, a temple was constructed in Dervan in his honor.
