Devi Sahab

Baba Devi Sahab (1841–1919) was one of the leaders of the Sant Mat religious movement, popularizing it throughout North India and Pakistan.
Early life.
It is said that his parents had been childless for a long time before his birth. The tradition holds that when Devi Sahab was nearly four years of age, Sant Tulsi Sahab visited his house again and prophesied that he would one day turn into a great sant.
Later life.
Baba Devi Sahab lived a simple life as a postal clerk while practicing his spiritual discipline. He voluntarily retired early and lived his latter years in Moradabad in the state of Uttar Pradesh. He was a kind teacher and had a large following. Baba Devi Sahab says:
Spiritual mission.
Baba Devi Sahab took forward and enriched the spiritual legacy of Sant Tulsi Sahab of Hathras (U.P.) by holding Satsangs and propagating the message of Santmat to different portions of the Northern and the erstwhile North-Western India that included parts of what is now Pakistan.
He eventually located his Ashram, base camp, at Moradabad/Muradabad, Uttar Pradesh. However, before that he is said to have spent a few years at Agra also where, it is said, he attended Satsang of Rai Bahadur Shaligram Ji (Hazur Rai Saligram Bahadur, later popularly also known as Huzur/Hazur Maharaj) who was the successor of Sant Radhaswami Sahab.
Padma Das Ji, a devotee in the Radhaswami tradition of Santmat and a close friend of Baba Devi Sahab, is said to have invited him to Agra to attend Satsang there. It is Padma Das Ji who is said to have introduced Baba Devi Sahab to Rai Bahadur Shaligram Ji (Hazur Rai Saligram Bahadur).
