Firewood becomes ash, and it does not become firewood again. Yet do not suppose that the ash is future and the firewood past. You should understand that firewood abides in the phenomenal expression of firewood, which fully includes past and future and is independent of past and future. Ash abides in the phenomenal expression of ash, which fully includes future and past. Just as firewood does not become firewood again after it is ash, you do not return to birth after death.
