Loïc Kōshō Vuillemin

Loïc Kōshō Vuillemin is a Swiss-French Sōtō Zen monk in the Deshimaru–Kōsen line and the son of Vincent Keisen Vuillemin ("Fils du maître zen Vincent Keisen Vuillemin")^[1], founder of the Dōjō Zen de Genève and a direct disciple of both Deshimaru and Étienne Mokushō Zeisler. He grew up immersed in Zen practice from early childhood, integrating zazen, the kesa, and monastic sangha life into his upbringing^[1].

At age twenty-one he received monastic ordination from Stéphane Kōsen Thibaut in 1998 and became his disciple^[1]. From 2010 he settled at the temple Yujō Nyūsanji as its guardian and caretaker^[1], one of the principal builders of the Caroux temple in its first decade. In 2013 he received the dharma transmission from Kōsen ("reçoit de son maître, en 2013, la transmission du dharma faisant de lui maître Kosho, 84e patriarche")^[1], at age 37, becoming the 84th patriarch of the Sōtō line^[1].

He later left the temple with his family and now lives in the South Sinai (Egypt), where he developed the practice he calls *Deep Zen — Meditation and Freediving*, fusing zazen breath training with apnea diving^[1]. The combination has made him one of the most distinctive contemporary teachers in the Kosen Sangha network^[1][2].
