The Rōkoan hermitage arose to meet the needs of practitioners, both in Kyoto and from abroad, seeking to further their practice. Practicing here is a precious chance to devote ourselves wholeheartedly and, whenever others are present, do what we can to support their practice while living together in harmony. Zen practice is the core, zazen is the natural focus: several hours of concentrated sitting – on your own or with others – every day. There is the opportunity for regular one-on-one. It is not a guest house, it is not a monastery.
Do not seek outwardly, but get hold of “it,” which gushes out of your own mind. If you foolishly look after others’ treasures saying that it is so written in this holy book, or it is thus explained by that wise man, you can never pass through this gate of no-gate.
