The sound only could be produced by hiting of two objects or either by rotation of any object. In human body these 56 metalic chakras; on rotatoin they produce different different sound waves which only reaches the throught where the produced sound gets expanded with swara and Gramer is given by mouth and sound of one letter comes out of the body.
The vedic language sanskrit only contains all 56 sounds and that too full in pronounsation which no other language of the plannet has. When the chakra rotates the nadis get enlarged due to pressure generated by rotation of the chakra. When the nadis get enlarged the whole energy flow system is maintained automatically perfect.
This is the main reason why the human of satyuga enjoyed a healthy life where as human of present time is entangled into plenty of diseases. The energy flow system is the main and the effective system which the human body has to improve imedeatly. Once the sound wave gets generated its vibration always remain inside the universe.
The sound is only thing which bears heavy energy and gets the protons charged by important words (only vedic mantras), the neutrons get charges by common words and the electrons get charged by bad words. The sound is the majour part on the planet and human of present time is far away from vedas as the human left the chanting of vedic mantras. The electrons are charged with bad words very heavily that is why only the present time is called ghor kalyuga.
If a body wants to live a healthy life it has to adopt chanting of Rudra mantras, as without that the body will suffer from diseases like diabities, colastrol, Cancer, BP, thyroied etc. All these types of diseases are the diseases caused only due to non proper energy supply inside the organ.
Different-different country people start suffering after the age of 45 years by different diseases depending upon the language they speak. The sound only makes up the mentality of human and this is only the reason different countries people have different mentality.
Only INDIA being a spiritual country have plenty of mentality peoples. India has maximum languages in the world which no other country has. There is the existance of only three types of words, the Important words (vedic mantras), the common words (Language other than vedic Sanskrit) and the bad words (negative vibrations). The sound only has its impact on brain and mind of human body as well as all the matter present in all states around body.
How does sound gets generated inside human body
