Past
True learning happens through meditation. Meditation means putting aside the past and looking into the present, making an immediate contact with the now and the here -- because God is now, God is here. God is always now and always here.
Mind lives in the past because it lives in knowledge. Knowledge means that which you have known, understood, learned. And existence is now and mind is then, existence is here and mind is always there. Mind looks backwards; it is like a rear-view mirror. If you are backing your car the rear-view mirror is okay, but if you are going forwards then it is dangerous to go on looking in the rear-view mirror. And if you become fixated on the rear-view mirror you are bound for an accident. You are in great danger, you are being suicidal. Life moves al ways forwards; it has no possibility of going backwards.
When the first Ford car was made it had no reverse gear -- that's how life is. The reverse gear was added later on -- from experience, because when you wanted to come back home you had to go miles around to do it. Then the thought happened that it would be better... even if you had gone just a few feet ahead of your house you could not come back; you had to take a long route. Maybe you had to go around the whole town, then you could come back. Then the reverse gear was added to it.
But God has not yet added any reverse gear. There is really no need to go back. The past evaporates -- there is no past. It leaves only traces in your memory system; otherwise it is not there. Existence is always present; past is only memory and future is only imagination. There is no future, no past. That which exists is the only real thing, and mind does not allow you to be in contact with it. How can you learn? How can you experience? Your experience cannot be wholesome, healthy. It will be sick, it will be unhealthy. And it has turned every person almost into a monster.
Your head goes on becoming bigger and bigger, and everything else has become so shrunken that it Is almost disappearing. People are just like heads, with small legs and hands just heads. This is a state of being a monster. Man HAS become a monster: he has lost all balance, all harmony. The head has exploited everything; it has destroyed your organic unity. It is like a parasite that goes on becoming bigger and bigger at the cost of your totality.
