Son of Zen Master Vincent Keisen Vuillemin, Loïc has been around the Zen environment since a very young age. Samu, genmai, zazen, the kesa, the sangha, Master Kosen, and the social life of modern monks naturally integrated into his education and development into adulthood.
However, it was only at the age of 21 and following certain initiatory experiences that he decided to take the form of a monk in turn. The quest began for him: to join Master Kosen, become his disciple, and help his sangha. The goal was clearly marked, Loïc abandoned his ethnobotany studies and settled in an abandoned gas station in the suburbs of Geneva to get as close as possible to the dojo that had instructed and supported him until then. Only one watchword: practice relentlessly. He sewed a black kesa and received monk ordination from Master Kosen in 1998, who then urged him to undertake biology studies.
Loïc spent 6 more years in Geneva between practice at the dojo and university studies, which he completed without finishing his doctoral thesis. He then attempted a departure for Montpellier where Master Kosen practiced daily, but ended up settling in Amsterdam with Hira Hosen, who would become his lawful wife. They lived there for two years before taking the southern route together again. After a difficult start, Master Kosen agreed to house the couple and take Loïc as his secretary. He then formally became his disciple.
It was a few years later, having become the father of an only daughter, that the temple appeared, of which he assumed general maintenance from the beginning. He settled there with his family in 2010 as a guardian and received from his master, in 2013, the transmission of the Dharma, making him Master Kosho, the 84th patriarch of the lineage. He was then 37 years old.
In 2017, after accomplishing a gigantic samu and achieving the feat of obtaining for the temple the approval of public opening standards, Kosho made the decision to return to the social world with his wife and daughter. He then undertook to live from his passion: freediving.
Now settled in Egypt, in South Sinai, he teaches the multiple aspects of the Way, breath, and letting go.
He also develops an education concept merging the practice of Zen meditation with learning freediving called Deep Zen: Meditation and Freediving
