When I say drop all hope, I mean be so intense in the moment that there is no need for the future. Then there is a turning, a transformation. The very quality of time changes for you it becomes eternal.
What can you do with hope?
In fact, what can you hope?
You cannot hope for the new.
You can only hope for the old, that which has happened before — maybe with a little modification here and there, a little more decorated. But hope is nothing but past: you have lived something, you have experienced something, and you again and again hope for it. It is a repetition; it is circular.
Hope means simply projecting the past into the future again: you loved a man yesterday, you want to love the man tomorrow also. And you know that yesterday was not a fulfillment, hence the hope. Yesterday was not enough, hence the hope. You missed something yesterday. Now that missed gap is torturing you; it is creating agony. You hope that again tomorrow that man will be available to love you, and tomorrow you will really love.
But between yesterday and tomorrow is today. If you really want to love, then why not be herenow, today? Otherwise, when today will have become yesterday you will again start projecting it. Incomplete experiences are projected. Uncompleted desires are projected. If you really love totally this moment, you will never think about this moment again. It is finished, it is complete, it is perfect. It disappears, it leaves no trace on you.
