The essence of the universe is energy, frequency and vibrations. The Vedas state that the making of the infinite Spirit (Shiva) was through a reverberating sound energy of the consciousness called the Naad. This sound was “unstruck”, which means that it was produced without any two things striking against one another, that is, without friction. Another legend advocates that years after the Big Bang, the universe started singing when Shiva played his damru (drum) the first time. Vast sound waves expanded through the primitive cosmos, and the tremors which arose then, can still be felt today. Naad or cosmic sound has also been described in the Bible, wherein, according to St. John, “In the beginning was the Word, and the Word was with God, and the Word was God”. Buddhism has its own version of ‘Naad’ as ‘a flaming sound’ and in Islam it is ‘a Kalma’.

In order to understand the importance of Naad, the best way is to look closely at ourselves. As we breathe, the vital wind called ‘Pran’ passes through our nostrils into our body, pulsates and vibrates in the form of heart beat and speaks as it passes through the wind pipe/throat. The speech, hence produced is the ability and the power of Pran to generate sound at the micro level of our existence. But at the macro level, the Pran termed as ‘Transcendental Pran’, is responsible for the speech of the Supreme Conscious and is called as ‘Brahmnaad’ (Brahm = Br + Ahm = “Br” means to say or to grow/expand, “ahm” is the Supreme Vibration and Nada is sound), generally known to all as the sound of God. Like all sound waves, the Brahmnaad also needs a medium to travel – ‘ether’, which is an enormous ocean of sound waves. While travelling through the ether, the Naad produces vibrations, therefore it becomes the primary source of ‘vibratory energy’. The vibrations give rise to the second component called the ‘wind’ and the dormant energy that is present in these vibrations is responsible for the generation of ‘light’. The ‘Naad’ is indeed the most important link between Brahm and the Pran of an individual and all the countless powers of creation have their origin in and work through this ‘Naad’.

Brahmnaad is like a music played by the supreme consciousness. When the spiritual practitioners such as yogis are able to hear this cosmic sound, which vibrates as the cosmic waves in the form of the word OM (AUM) or SOHAM and when they realise that the Naad is actually coming from their own heart as a subtle vibration and getting enhanced by the compatible electromagnetic waves generated by their own brains, it is then only that they are able to establish a direct link between themselves and the Supreme Brahm. The Naad, therefore, is the actual Reality that exists, but since it is so subtle that it requires a proper training and a discerning student to catch its frequencies. A beginner of spiritual science can still hear this cosmic Naad by closing one’s ears and internally hear the roaring sound of the blood flowing throughout the physical body. Some have also named it as the ‘Sound of Silence’.

The Hanso-panishad of Shukla Yajur Veda has precisely described the different types of sounds radiating out of Brahmnaad from low to high frequency and the different types of emotional feelings the body experiences in terms of reflexes as a result, depending upon the spiritual progress of the aspirant –

  • Clinking of bracelets – this first sound creates a tickling sensation
  • Tinkling of anklets – creates stiff muscles leading to spasms
  • Clanging sound of a gong hitting a brass bell – leads to perspiration from the body
  • Sharp blowing of a conch shell – creates tremors in the head
  • Playing of stringed musical instrument (e.g., lute, harp, guitar) – creates saliva to dribble out of the mouth
  • The clap or clunking sound of cymbals – causes ‘a rain of Amrit’ ( tears of bliss)
  • Sound of a flute – blesses the aspirant with the most secret knowledge
  • Beating of tumbrels – facilitates the aspirant to speak in a mystical language.
  • Sound of drums – gives the aspirant mystical and divine powers of insight and vision.
  • Thundering of cloud – allows to acquire the inspirational and varied knowledge related to the Supreme Brahm.

The spiritual aspirant completes the journey of his Atman (soul) by tuning into the correct frequency of the Naad vibration originating from his heart and brain. This explains how and why the yogis have mystical power to leave their bodies and wander around in the spirit (astral roaming) and then come back to rejoin their bodies. This also explains the phenomenon of rebirth in the form and spot which matches the individual’s frequency with that of the cosmos at the time of his one life time death.
