Science of Mantras

In Indian vedic culture Mantras are very important &; integral part of system .as every rituals are performed with Mantras.

It is  very important that these mantras are designed in such way that it create a impact  on human body it resonate  with different parts of the body .

It is a great research of our Rishis in ancient time in indian culture that despite any modern equipment they studied & implemented  the usage of sound energy .

As per Jonathan Goldman
Some believe that the recitation of sacred mantras actually causes the physical and etheric bodies to change their vibrational frequency level-becoming more attuned if you like, with divine energy. Thus, when one chants a mantra for an extended period of time, to invoke, for example some deity, the higher energies of that deity will encode itself upon the chanter. This is one purpose for much mantric chanting—to become one and unite with the energy of the deity that one is chanting for. If the person has some sickness or imbalance, this imbalance can frequently be released by having the energy of the deity encode itself upon the person. This actually comes from the concept of vibrational (as opposed to allopathic) medicine, which is the basis of many healing modality, including homeopathy and acupuncture—that all the universe including our bodies, is simply made of vibration—a concept, incidentally, that the new Superstring theory of physics supports. Everything is in a state of vibration and when we are in a natural, resonant vibration, we are in a state of health. But if some part of the body begins to vibrate at a counter frequency, the energy becomes stuck and disease sets in. Therefore, by mantric chanting, one can cause stuck energy to become released, and we can return to our natural state of resonance, effecting a cure.

it is easily observed with mantras like" OM" Gayatri Mantras , etc  we can easily observed the transformation in the body before & after chanting .

unfortunately due to advance in education these science is restricted to few people & for their own interest they spressed the knowledge for long time nowadays no of other & the young ones of the same community are exposing the inner core knowledge to science fraternity . which helping the mankind .
