Gérard Blitz was a zen monk, consecrated by Taisen Deshimaru, and a yoga master educated by T.K.R. Krishnamacharia.

Friend of Krishnamurti and T.K.W. Desikachar, he brought this yoga tradition, based on Patanjali's Yoga Sutra, to the Western World, developing clear and simple teaching methods suitable for everyone.
Yoga schools associated with I.I.R.Y. follow his teaching.

The institute includes Active Members and Teachers, who qualify after attending the 4 year Education Program created by Gérard Blitz for the 'European Union of Yoga Federations', that he also founded.

I.I.R.Y. teachers are educated by a unique master, who is responsible for ensuring the authenticity of the teaching.
