According to Måns Broo's* Joogan [yaw-gun] filosofia (Philosophy of yoga) for instance these concepts in YS are of Buddhist origin:
prajñaa, Rtambharaa, klesha, aashaya, nirodha, dharma, lakSaNa, dharmamegha, etc. * ~ /mawns brew/; å is so called Swedish o, pronounced probably always approx. as aw in law. From http://petriraisanen.com: http://petriraisanen.com: 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.
