Osho introduces a small experiment: “You are looking at the mirror, your own face in the mirror, your own eyes in the mirror…”
The Taoist experience is that this energy that you spend in your extroversion can be more and more crystallized rather than spent if you learn the secret science of turning it backwards. It is possible; that is the whole science of all methods of concentration.
Just standing before a mirror some day, try one small experiment. You are looking at the mirror, your own face in the mirror, your own eyes in the mirror. This is extroversion: you are looking into the mirrored face – your own face, of course, but it is an object outside you. Then, for a moment, reverse the whole process. Start feeling that you are being looked at by the reflection in the mirror – not that you are looking at the reflection but the reflection is looking at you – and you will be in a very strange space. Just try it for a few minutes and you will be very alive, and something of immense power will start entering you. You may even become frightened because you have never known it; you have never seen the complete circle of energy.
And although it is not mentioned in Taoist scriptures this seems to me the most simple experiment anybody can do, and very easily. Just standing before the mirror in your bathroom, first look into the reflection: you are looking and the reflection is the object. Then change the whole situation, reverse the process. Start feeling that you are the reflection and the reflection is looking at you. And immediately you will see a change happening, a great energy moving towards you.
In the beginning it may be frightening because you have never done it and you have never known it; it will look crazy. You may feel shaken, a trembling may arise in you, or you may feel disorientated, because your whole orientation up to now has been extroversion. Introversion has to be learned slowly slowly. But the circle is complete. And if you do it for a few days you will be surprised how much more alive you feel the whole day. Just a few minutes standing before the mirror and letting the energy come back to you so the circle is complete… And whenever the circle is complete there is a great silence.
The incomplete circle creates restlessness. When the circle is complete it creates rest, it makes you centred. And to be centred is to be powerful – the power is yours. And this is just an experiment; then you can try it in many ways.
Looking at the rose flower, first look at the rose flower for a few moments, a few minutes, and then start the reverse process: the rose flower is looking at you. And you will be surprised how much energy the rose flower can give to you. And the same can be done with trees and the stars and with people. And the best way is to do it with the woman or man you love. Just look into each other’s eyes. First begin looking at the other and then start feeling the other returning the energy to you; the gift is coming back. You will feel replenished, you will feel showered, bathed, basked in a new kind of energy. You will come out of it rejuvenated, vitalized.
