Vibrational medicine is the intentional use of a frequency to positively affect another frequency or to bring an organism into balance.
Nāda yoga (नादयोग) is an ancient Indian metaphysical system. It is equally a philosophical system, a medicine, and a form of yoga. The system's theoretical and practical aspects are based on the premise that the entire cosmos and all that exists in the cosmos, including human beings, consists of sound vibrations, called nāda. This concept holds that it is the sound energy in motion rather than of matter and particles which form the building blocks of the cosmos. Nāda yoga is also a reverential way to approach and respond to sound. In this context, sound and music carry a spiritual weight more meaningful, respectively, than what sensory properties normally provide. Sound and music are considered to play a potential medium/intermediary role to achieve a deeper unity with both the outer and inner cosmos.
There exists in India a secret knowledge based upon sounds and the differences of vibratory modes found on different planes of consciousness. If we pronounce the sound OM, for example, we clearly feel its vibrations enveloping the head centers, while the sound RAM affects the navel center. And since each of our centers of consciousness is in direct contact with a plane, we can, by the repetition of certain sounds (japa), come into contact with the corresponding plane of consciousness. This is the basis of an entire spiritual discipline, called "tantric" because it originates from sacred texts known as Tantra.
The basic or essential sounds that have the power to establish the contact are called mantras. The word comes from man; meaning mind, and tra, which means protection or instrument. Thus, a mantra is a tool for protecting our minds from the traps of non-productive cycles of thought and action. Mantras serve as focusing devices for making the mind one-pointed and calm. A mantra can be used to awaken the mind from its habitual sleep of ignorance.
Mantras do not limit themselves to that purpose. They, usually secret and given to the disciple by his Master, are of all kinds (there are many levels within each plane of consciousness), and may serve the most contradictory purposes. By combining certain sounds, one can at the lower levels of consciousness –generally at the vital level– come in contact with the corresponding forces and acquire many strange powers: some mantras can cause death (in five minutes, with violent vomiting), some mantras can strike with precision a particular part or organ of the body, some mantras can cure, some mantras can start a fire, protect, or cast spells. This type of magic, or chemistry of vibrations, derives simply from a conscious handling of the lower vibrations. But there is a higher magic, which also derives from handling vibrations, on higher planes of consciousness. This is poetry, music, the spiritual mantras of the Upanishads and the Veda, the mantras given by a Master to his disciple to help him come consciously into direct contact with a special plane of consciousness, a force or a divine being. In this case, the sound holds in itself the power of experience and realization – it is a sound that makes one see.
