Hari Krishnas
A group of Hari Krishnas singing on the streets of Ottawa.
The Hare Krishnas have to be one of the more famous sects of Hinduism out there. They are the group famous for singing — all the time. The reason they sing is to express their devotion to the Hindu god Krishna. One of the paths to salvation outlined in the Bhagavad Gita is bhakti-yoga, or the path of devotion.
