Master Dogen wrote on Time (in Being-Time, Uji):
See each thing in this entire world as a moment of time.
Things do not hinder one another, just as moments do not hinder one another. …
Each moment is all being, is the entire world.
Reflect now whether any being or any world is left out of the present moment.
Master Dogen wished to convey that each moment of time and being is not anything apart from you. It is your existential time-and-being. So, he wrote in Uji:
Because real existence is only this exact moment, all moments of Being-Time are the whole of Time, and all existent things and all existent phenomena are moments of Time …
If Time does not take the form of leaving and coming, [a task done in the past] is the present as Being-Time.
If Time does take the form of leaving and coming, you yet have this present moment of Being-Time, which is just Being-Time itself.
So each moment is in itself the whole, but is it new?
Happy new moment?
