Everything in existence derives from the Supreme Consciousness

The Supreme Consciousness manifested itself as Transcendental Sound and Light. Thus, spiritual and subtle material universes and the gross physical universe were created. All worlds, the material ones included, are saturated with subtle Sound, which the ancient Indian scriptures called Nada. Sound is in minerals, plants, animals and within us. Every tree, flower, everything in existence emits sound, a vibration.
The oldest writings Vedas and Upanishads talk about the Sound – Shabda, Akash Bani and Udgitha, which permeates the physical universe, the astral, mental or causal, and spiritual worlds. Although matter has sound, it is too condensed, so this sound cannot be heard.
Laozi said that “Tao (Sound) is hidden and nameless, yet it sustains all and fulfils all.”
There is one principle that connects all these levels – the Sound, Music. Transcendental Sound takes on various forms when it descends down onto the lower worlds. Music governs everything. He who discovers the secret of Music, unveils the mystery of life. When we rise from the physical and enter the higher, subtle worlds, we hear Music.
Kabir says: “There, the whole sky is filled with Sound, and there that Music is made without fingers and without strings.”
And the Indian wise man Nanak wrote: “The Earth and the sky were made by Shabd (Sound), Shabd is the source of all light.”
Indian spiritual tradition speaks of two types of music: Anahata Nada, “unstruck sound” and ahata nada, “struck sound”. Ahata Nada is therefore physical sound, while Anahata Nada is the Sound of creation, the infinite Sound.
If external sound or music can be so very attractive, we can only imagine what the power and charm of the inner, transcendental Sound, Anahata Nada is like. It’s completely subtle, full of elixir. No one can resist its intoxicating power. It casts an unbreakable spell on the Soul.
Indian sage says: “Absorption in the Naam (Sound) brings Cosmic Awareness. Those who engage in the Naam are ever blissful.”
Plotinus wrote: “Thus all music – since its thought is upon melody and rhythm – must be the earthly representation of the music there is in the rhythm of the Ideal Realm (Spiritual world).”
All spiritual traditions talk about inner Sound:
The Vedas say that Nada was the Sound that created the entire cosmos. In the Quran it is written that Kalam was the creator. The Bible and the Dead Sea Scrolls speak of the Word, the Sound, which is the creator of everything. In Adi Granth, the holy book of the Sikhs, it is said that all of creation emerged from Shabda or Naam, which keeps everything alive. The planets, the Sun, the Moon, Earth and spiritual dimensions are governed by the same power – the power of Sound. No place exists where this power would not be present. Sound is ubiquitous. In the Upanishads it is called Udgitha, the music of divine realms, or Pranava, the Sound that can be heard without ears. The Greeks named it Logos, Pythagoras cal led it the Music of the Spheres, the Chinese called it Tao, Gautama Buddha said it was Buddhi, the Sufis, the Sauti-I-Sarmadi.
Sound is light, life, knowledge, nectar and love. When the Soul in meditation listens to inner Music, it is elevated from the physical and subtle bodies and travels onto spiritual planes from whence Sound derives. It is here that an enchanting melody can be heard.
Hafez has this to say about the latter: “The Sound is coming from the Divine Home. Why are you entangled in the snares of the world?”
