We are seeing, then, that our experience is altogether momentary. From one point of view, each moment is so elusive and so brief that we cannot even think about it before it has gone. From another point of view, this moment is always here, since we know no other moment than the present moment. It is always dying, always becoming past more rapidly than imagination can conceive. Yet at the same time it is always being born, always new, emerging just as rapidly from that complete unknown we call the future. Thinking about it almost makes you breathless.
