MEDITATION

is a form of breathing, posture and chanting set of exercises which are designed to achieve enlightenment or at least the week's winning Lotto numbers. Contemplation from my understanding is an all together different animal.

Anyway, there are a number of ways to rate the bio field effect of Mantras used in meditation. Brain waves of meditators could let us know which mantras have what specific frequency modulation on the dominant brain waves. We could chart out the geometric shapes each frequency has.

But all joking aside, many millions of people meditate daily with sometimes "Privately derived" special words. The saints of India have said that if you chant in meditation you must do so 108 times repetition or at least 54 times. Studies I've heard of (TM website) suggest crime rates go down in neighborhoods that have weekly group meditation sessions.
