According to modern science, the whole existence is vibration. A vibration is fundamentally a kind of sound. This essentially means that the whole existence is an amalgamation of sounds. In the yogic system, a few of these sounds have been identified as keys to access deeper dimensions of life.
Nada Yoga uses the power of sound to activate a particular kind of energy in different parts of the body, bringing a lasting sense of inner pleasantness. This science of benefiting from certain sounds is a powerful possibility, which when transmitted with the necessary basis and sanctity, creates tremendous wellbeing.
