These tenses-past, present and future-are not the tenses of time; they are tenses of the mind. That which is no longer before the mind becomes the past. That which is before the mind is the present. And that which is going to be before the mind is the future. Past is that which is no longer before you. Future is that which is not yet before you. And present is that which is before you and is slipping out of your sight. Soon it will be past.
