Dogen's Genjo Koan: Firewood Becomes Ash

In conventional understanding, firewood becomes ash, and the two have a continuous relationship. We have a concept that time moves forward on a journey and thus has spatiality. But Dogen says that each thing—firewood or ash, you or me—is its own full expression in the moment. There is no separation between the time we abstract and imagine, that we control and move through, and our very being. Time is all being, and all being is time. The pine is time and the bamboo is time. We can let go of all the anxious attempts to fix this being that imagines itself moving through time, separate and lonely. The time-being of all things, the interpenetration of all beings, is constantly at work.
