Music floats into those realms where language struggles.
The breath, the heartbeat, the pulse: every proof of ‘being alive’, is musical. There is harmony, there is a fixed rhythm and hence there is ‘life’ and ‘energy’. That’s is perhaps the reason music/sound is referred to as “Nada-Brahma” (“Nada” meaning sound/music and Brahman meaning creational/existential energy)”. Human body-mind is a flux of different energies at play, be it the energies associated with joy, sadness, anger, stress and so on.
These emotions and many more are abundant in the human mind. Listening to music during happy times stimulates positive vibrations in the body-mind ecosphere. Listening to it during a stressful state of mind can be equally cathartic. In any emotional state an individual experiences, it helps calm or even tranquillizes the mind and a tranquil mind is meditative.
It’s believed that music is a complete tool which activates the whole human body and mind, since it engages both, the physical body and the Metaphysical mind totally, thus helping achieve a balance between the two. A balanced body-mind is a treasure of positivism.
Indian music is so designed by our ancestors that the 72 mainstream(Melakarta) ragas in the Carnatic system of music are supposed to be associated with 72000 naadis(associated with the nervous system on a physical level) of a human body. Naadis are considered those channels which carry the life energy, Praana. Certain ragas sensitize certain naadis in the body and hence are therapeutic, as far as human body-mind is concerned.Scientifically speaking, The system of rhythm (tala) works on the logical part of the brain while ragas work on the emotional part of the brain.
