Måns BrooMåns began his yogic path in his late teens, when he joined the Hare
Krishnas and lived in an ashrama, devoting himself fully to the path of
bhakti-yoga. After about a year he moved back into the world, trying to apply
the teachings he learned in the ashrama, and also delving more deeply into the
teachings of the tradition of Krishna-bhakti. These studies eventually led to a
Ph.D. in Comparative Religion from Åbo Akademi University, Finland, where he
works as adjunct professor. Måns has also studied Sanskrit at Uppsala
University, Sweden, and (together with Martin Gansten) published a critically
acclaimed first ever complete translation of the principal Upanishads into
Swedish. He has recently published an introduction to the Hindu scriptures in
Swedish and a book of religious poetry in Sanskrit. He is also the
editor-in-chief of a Finnish yoga-magazine Ananda and teaches and writes about
yoga philosophy.
