"Mantras are not small things, mantras have power. They are the mind vibration in relationship to the Cosmos. The science of mantra is based on the knowledge that sound is a form of energy having structure, power, and a definite predictable effect on the chakras and the human psyche."
~ Yogi Bhajan
Mantra is the use of sound to affect consciousness; man means mind and trang means wave or projection. Everything in this world, down to the subatomic level, is in constant motion, vibrating. The denser a material, the more slowly it moves; often the vibration is so slow or so fast that we can’t notice it with our direct senses. This vibration is pure energy.
Sound and Vibratory Frequency
There is a vibratory frequency that corresponds to everything in the Universe. Happiness or sorrow, joy or regret are vibratory frequencies in the mind. When we chant a mantra we are choosing to invoke the positive power contained in those particular syllables. Whether it’s for prosperity, peace of mind, increasing intuition, or any other possible benefits inherent in mantras, simply by chanting them we are setting vibrations into motion that shall have an effect. It doesn’t actually matter if we understand the meaning of the sounds or not.
Chanting mantra produces specific vibratory frequency within the body. The sounds and thoughts produced by the body and mind radiate out from you. The vibratory frequency of a mantra draws to you whatever you are vibrating. You are like a magnet attracting vibrations to you by what you send out. As a vibration, a mood, a state of being that results from chanting, mantra is compatible with all belief systems.
In addition to the vibrations set in motion, something else happens when you chant. This is really important. There are eighty-four meridian points, or pressure points, in the roof of the mouth. Every time you speak, you stimulate them and their associated glands and organs—with the tongue. And every time you chant a mantra, you are tapping out a particular sequence, rhythm, and position that initiates a chemical reaction in the brain and body. It’s as if you have an electronic, computerized security system in your mouth. Punch in the right code on the upper palate and you gain entry to the brain and your inner chambers of higher consciousness![From Kundalini Yoga: The Flow of Eternal Power, by Shakti Parwha Kaur]
