"Ordinarily, time is divided into these three tenses: past, present, future. The division is basically wrong, unscientific. Because present is not part of time. Past and future only are parts of time. Present is beyond time. Present is eternity.
"Past and future are part of time. Past is that which is no more, and future is that which is not yet. Both are non-existential. Present is that which is. The existential cannot be a part of the non-existential. They never meet, they never cross each other's way. And time is mind; past accumulated is what your mind is.
"What is your mind? Analyze it, look into it. What is it? – just the past experiences piled up, accumulated. Your mind is just a blanket term, an umbrella term; it simply keeps, holds, your whole past. It is nothing else. If by and by you take your past out of the bag, the bag will disappear.
"If past is the only reality for the mind, then what can the mind do? One possibility is that it can go on chewing, re-chewing the past again and again. That's what you call memory, remembrance, nostalgia. You go again and again backwards; again and again to the past moments, beautiful moments, happy moments. They are few and far between, but you cling to them. You avoid the ugly moments, the miserable moments.
"But this you cannot do continuously because this is futile; the activity seems to be meaningless. The mind creates a 'meaningful' activity – that's what daydreaming about the future is.
"The mind says, 'Yes, past is good, but past is finished; nothing can be done about it. Something can be done about the future because it is yet to come.' So you choose out of your past experiences those which you would like to repeat again, and you drop experiences that were very miserable, painful; that you don't want to repeat in the future.
"So your future dreaming is nothing but past modified, better arranged, more decorated, more agreeable, less painful, more pleasant. This your mind goes on doing. And this way you go on missing reality.
"Meditation simply means a few moments when you are not in the mind, a few moments when you slip out of the mind."
