Mantras effect on Mind and body
In its most rudimentary form, a mantra is made of syllables which exert their influence by means of sound (vibrations). As one would have personally experienced, different syllables have different vibration patterns which affect different parts of the body. Each syllable resonates with certain organ or part of the body. Every thought or feeling that we have is on a vibratory frequency. By using mantras we can direct the mind into a higher vibratory frequency. For thousands of years, mystics and yogis have used mantras for mental and spiritual transformation
For example, by chanting “aaaaaaa”, one can feel the sensation and hence resonance of nervous system in the stomach and chest region.
Chanting “ooooo” creates sensations in throat & chest region and resonates with them.
Similarly, chanting/humming “mmmm” resonates with the nasal cavity as well as in skull/brain region.
when we concatenate (join together) the above syllables into one mantra. We get the AUM mantra which when chanted sequentially activates the stomach, spinal cord, throat, nasal and brain regions.The energy moves from the abdomen all the way up to the brain, thereby channelizing energy and activating the spinal cord and brain.
One of the most popular claims made by Yogis is that chanting Om mantra improves our concentration, gives peace and steadiness to our mind, reduces mental stress and clears all worldly thoughts.
In the ancient tradition of meditation, it was said that mantra and meditation are like two sides of the same coin. Certainly there are some techniques that do not use mantra as a way of deepening the meditative state, but these are generally limited to breath awareness—and such techniques can take students only so far. They cannot help them to attain the highest state. But when students meditate on a particular mantra and make a conscious effort to focus the mind on that mantra, this finally leads the mind to silence. All sounds proceed from silence; the mantra leads the student back to that silence which is called samadhi, nirvana, or the state of tranquility. Thus, among all the methods of meditation, mantra is the most profound and advanced.
