Shikantaza, our zazen, is just to be ourselves. When we do not expect anything we can be ourselves. That is our way, to live fully in each moment of time. This practice continues forever.
We say, “each moment”, but in your actual practice a “moment” is too long because in that “moment” your mind is already involved in following the breath. So we say, “Even in a snap of your fingers there are millions of instants of time.” This way we emphasize the feeling of existing in each instant of time. Then your mind is very quiet.
So for a period of time each day, try to sit in shikantaza, without moving, without expecting anything, as if you were in your last instant. In each inhalation and each exhalation there are countless instants of time. Your intention is to live in each instant.
