In the beginning there was nothing. From nothing the nada (=sound) OM emanated. This pranava, the prime sound OM, was created by Shiva with his damaru (=drum). SHIVA =Symphony Harmony Initiation Vibration Awakening.
With OMKAR Shiva nature created out of the 5 elements the entire existence, energy, nature, cosmos and the imagination of the world. Sadashiva is the Lord of the 5 elements: air, water, fire, space and earth.
The prime sound of AUM is the sound of a the breath, which is Shivas blessing itself. To know Shiva, know your breath. From the first technique of Shiva Dhyan Yoga, everything from the internal to the external cosmic life evolves.
