This is not going to happen. It is not a question of cause and effect. These waves in the mind are not the cause of meditation; they are, on the contrary, the effect. But from the effect you cannot move towards the cause. It is possible that by biofeedback you can create certain patterns in the mind and they will give a feeling of peace, silence and serenity to the person. Because the person himself does not know what meditation is and has no way of comparing, he may be misled into believing that this is meditation. But it is not, because the moment the biofeedback mechanism stops, the waves disappear, and the silence and the peace and the serenity also disappear.
And you may go on practicing with those scientific instruments for years; it will not change your character, it will not change your morality, it will not change your individuality. You will remain the same.
Meditation transforms. It takes you to higher levels of consciousness and changes your whole lifestyle. It changes your reactions into responses to such an extent that it is unbelievable that the person who would have reacted in the same situation in anger is now acting in deep compassion, with love, in the same situation.
Meditation is a state of being, arrived at through understanding. It needs intelligence; it does not need techniques. There is no technique that can give you intelligence. Otherwise, we would have changed all the idiots into geniuses; all the mediocre people would have become Albert Einsteins, Bertrand Russells, Jean-Paul Sartres. There is no way to change your intelligence from the outside, to sharpen it, to make it more penetrating, to give it more insight. It is simply a question of understanding, and nobody else can do it for you – no machine, no man.
For centuries the so-called gurus have been cheating humanity. Now, in the future instead of gurus, these guru machines will cheat humanity. The gurus were cheating people, saying, “We will give you a mantra. Repeat the mantra.” Certainly by repeating a mantra continuously, you create the energy field of a certain wave-length, but the man remains the same, because it is only on the surface. Just as if you throw a pebble into a silent lake, and ripples arise and move all over the lake from one corner to the other corner, but they do not touch the depths of the lake at all. The depths are completely unaware of what is happening on the surface. And what you see on the surface is also illusory. You think that ripples are moving; that’s not true, nothing is moving.
When you throw a pebble into the lake, it is not that ripples start moving. You can check it by putting a small flower on the water. You will be surprised: the flower remains in the same place. If the waves were moving and going towards the shore, they would have taken the flower with them. The flower remains there. The waves are not moving; it is just the water going up and down in the same place, creating the illusion of movement. The depths of the lake will not know anything about it. And there is going to be no change in the character, in the beauty of the lake, by creating those waves.
