In the summer of 1970, Harbhajan Singh participated in an informal "Holy Man Jam" at the University of Colorado at Boulder with Swami Satchidananda, Stephen Gaskin of The Farm in Tennessee, Zen Buddhist Bill Quan-roshi, and other local spiritual leaders.
A few weeks later, he organized a gathering of spiritual teachers to engage and inspire the 200,000 attendees of the Atlanta International Pop Festival on the stage between the performances of the bands.

All through the 1970s and 80s, as the Siri Singh Sahib of Sikh Dharma, Harbhajan Singh actively engaged in and chaired numerous inter-religious councils and forums, including the Inter-Religious Council of Southern California, the World Conference for the Unity of Man, and the World Parliament of Religions.
In 1999, he gave a presentation at the Parliament of the World's Religions in Cape Town, South Africa.
