Close the doors of your room and put a big mirror just in front of you. The room must be dark. And then put a small flame by the side of the mirror in such a way that it is not directly reflected in it. Just your face is reflected in the mirror, not the flame. Then constantly stare into your own eyes in the mirror. Do not blink.
This is a forty-minute experiment, and within two or three days you will be able to keep your eyes unblinking. Even if tears come, let them come, but persist in not blinking and go on staring constantly into your eyes. Do not change the stare. Go on staring into the eyes, your own, and within two or three days you will become aware of a very strange phenomenon. Your face will begin to take new shapes. You may even be scared. The face in the mirror will begin to change. Sometimes a very different face will be there which you have never known as yours.
But, really, all these faces belong to you. Now the subconscious mind is beginning to explode. These faces, these masks, are yours. Sometimes even a face that belongs to a past life may come in. After one week of constant staring for forty minutes, your face will become a flux, just a film-like flux. Many faces will be coming and going constantly.
After three weeks, you will not be able to remember which is your face. You will not be able to remember your own face, because you have seen so many faces coming and going.
If you continue, then any day, after three weeks, the most strange thing happens: suddenly there is no face in the mirror. The mirror is vacant, you are staring into emptiness. There is no face at all.
This is the moment: close your eyes, and encounter the unconscious. You will be naked – completely naked, as you are. All deceptions will fall.
