No-Mind
If the mind wants to comprehend reality, it will have to come out of the past and the future. But coming out of the past and the future, it is no longer the mind at all. Hence the insistence of all the great masters of the world that the door to reality is no-mind.
Slip out of the mind, and you will know what it is: the beginningless, the endless. Remain confined to the mind, and you will be puzzled; reality remains inconceivable.
I cannot explain it to you, because in explaining I will have to use the mind. Trying to understand it, you will have to use the mind. I can be silent with you, and if you can also be silent with me then there is understanding. Understanding is not of the mind. Then there is great intelligence, great insight. Suddenly you know, and you know from a totally different center of your being; you know from the heart. Your knowing has the quality of love, not of knowledge. Your knowing has the quality of transcendence. It is no longer scientific knowledge, reducible to concepts. It is poetic vision, it is mystic experience.
If you really want to understand, you will have to lose the mind. You will have to pay the price of losing the mind. But if you insist, "I have to understand through the mind," then only one thing is possible. The mind will convince you, slowly slowly, that there is nothing which is beginningless, nothing which is endless, nothing which is indefinable, nothing which is unknowable.
