Cosmic Sound

Definition - What does Cosmic Sound mean?

In Hinduism and yogic philosophy, the cosmic sound is the auditory manifestation of Brahman, the Absolute Truth or Ultimate Reality. It is verbalized as the mantra, Om (also spelled Aum). According to the Bhagavad Gita, “God is the sound of Om.”

The cosmic sound is associated with the creation of the universe. It is believed that before creation, the humming of energy existed. That energy became the vibration of creation and so the universe was created out of the ever-present sound of Om. This cosmic sound and its vibration still exists around and inside everyone.

Yogapedia explains Cosmic Sound

Cosmic sound is also known by the Sanskrit term, nada. Nada yoga philosophy believes all things – living or inanimate – consist of nada. Through meditation, the yogi creates space for the cosmic sound. Likewise, the "Hatha Yoga Pradipika" text says when a yogi reaches the supreme state, the cosmic sound can be heard.

Today, chanting Om in concert with meditation brings one closer to unity with the universe. Depending on the specific tradition, this can also be called unity with the Divine, Absolute Reality, the Higher Self, God or Brahman, The energy of the universe enters the body, creating strength and energy, and the desire for possessions and attachments disappears because the yogi is one with all things.

Paramahamsa Yogananda said that this sound and its vibration can be found in all religions – in the Hum of Tibetan monks, the Amin of Muslims and Amen of Christians and Jews.
