This increasing charm attracts the mind by itself. The mind is pulled by the gravity of great happiness in that direction. It is a spontaneous march of the mind inward towards the field of bliss. It does not require any concentration or control of the mind. Concentration brings tension.
Concentration is a static process.
Transcendental Meditation is a dynamic process that takes the mind from grosser levels to subtler levels of thought. It requires just the desire to learn, and as anything is learned from a teacher, so, too, Transcendental Meditation is learned from a teacher. For these past 40 years, millions of people have learned Transcendental Meditation and they are gaining enlightenment. Enlightenment means lack of darkness, absence of darkness. That is enlightenment.
