Sound vibrations are created when sound waves travel through a medium such as air or water. These vibrations create a physical sensation that can be heard by the human ear. The term 'MANTRA' is derived from the Sanskrit language and refers to a phrase or set of words that are repeated in order to focus the mind and bring about a desired state of being. Mantras are often used in meditation and spiritual practices, and are believed to have a calming effect on the mind and body.
