Some time after 1945 he retired from worldly life and took sanyas vows, becoming a monk in the tradition of the Naga Babas, more exactly, in the Anandakara branch of the movement founded by Shankaracharya.

In the late 1970s he lived at Swayambunath (near Kathmandu) where he received many visitors and gave courses in Kriya Yoga practice.

He taught that there is a cyclic cosmic process of involution and evolution, and he developed a system of correspondences – a "Cycle of Synthesis" – between levels of Kriya Yoga practice, the five koshas, the planets, the kayas, the Yugas, the cakras, the stages of organic evolution and the Jungian psychological types.

The longer manuscripts, "Search of Self," an unfinished autobiography, "Sadhana," a kriya yoga manual, and a detailed essay on his Cycle of Synthesis, are synthesized and updated as The Crazy Wisdom of Ganesh Baba, by Eve Neuhaus (2010).

He visited a Kriya Yoga center in France (which was established by his French followers), then went back to India.
