Mouna Arnaud Massin met Ojasvin in a seminar of the School « Yoga of Integral Learning » where he's been studying since 1999. Touched by the power and the beauty of the art of haka, he started to danse for himself and with friends to keep GMHH energy alive.
Thomas Studer, one of the first teachers trained by Waimaania & Ojasvin, introduced him to the other hakas and in 2012, Mouna participated to his first seminar with Waimaania & Ojasvin, followed by many others. Recognized for his capacity to transmit the GMHH in the right and authentic way, Mouna began his training as a teacher and graduated on the 5th of June 2016. He is training GMHH groups in France, leads introduction GMHH Seminars and is a facilitator in the Haka Rongo Aio 3 year formation.
