Selvarajan Yesudian, son of an Indian doctor, came in 1936 to Europe to study medicine here. In Hungary he got to know Mrs. Elisabeth Haich and began to give together with her lectures and courses about Hatha yoga. They wrote their first book Yoga and Health which reached an edition of 100 000 in Hungary within three years Today more than 1,8 millions in a lot of languages. The effect in the whole on people and particularly on the youth was astonishing. During the 2nd world war the Indian assisted his pupils and friends unshakably and remained to them a light and support. In 1948, however, every further yoga teaching was blocked by the communist government of Hungary. So Mr. Yesudian decided to emigrate with Mrs. Haich to North America. On the way to America they were asked by Switzerland friends to stay here. Yoga schools in Zurich, Bern, Basel, Saint Gallen, Lucerne, Olten, Schaffhausen, Lausanne, Geneva and summer courses in Ponte Tresa have developed themselves afterwards in all silence and became a blessing for thousands of searching persons. Selvarajan Yesudian returned into the source in October, 1998.
