Remember that there is no shortcut to meditation, and no mechanical device can be of any help. In fact, meditation needs no technique — scientific or otherwise. Meditation is simply an understanding. It is not a question of sitting silently, it is not a question of chanting a mantra. It is a question of understanding the subtle workings of the mind. As you understand those workings of the mind a great awareness arises in you which is not of the mind. That awareness arises in your being, in your soul, in your consciousness.
