“The discipline of zazen is the refusal to be manipulated by your own mind.”In this talk, Koshin Sensei reflects on the liberating power of discipline, the courage to make effort, and the serenity that comes not from outer conditions but from the clarity of mind itself. Drawing on the teachings of Shakyamuni Buddha, Dōgen Zenji, and Uchiyama Roshi, he explores how daily reverence for concentration allows the Dharma (wisdom) to flourish in our lives. From the story of Dōgen meeting the tenzo (head cook at a monastery) who walked 20 miles for mushrooms to the simple mirror-like nature of zazen, this talk invites us to return again and again to the freshness of the present moment.
