Nada yoga 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 matter and particles which form the building blocks of the cosmos.
Nada 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 our outer and inner worlds.
Nada yoga’s use of sound vibrations and resonances are also used to pursue palliative effects on various problematic psychological and spiritual conditions. It is also employed to raise the level of awareness of the energy centers called chakras.
