A day is set apart where the gathering stops. What is needed has already been provided the day before, so no one has to scramble at dawn. The provision was given in advance, and the striving can rest.
Enough is already here for the person who abides where they are. So much restlessness comes from leaving the present spot, chasing the next thing across the horizon of the mind. Staying put, without reaching, a person discovers that the moment they stand in was never lacking. Rest was never something to earn. A person only steps into what the sabbath already holds out to them.
