Above is the HU Song of the Eckankars (Eckankar is a religious and spiritual movement that identifies God with Sound and Light).
.Just as many traditions believe that the “OM” is the original creative sound, there are traditions that believe that this energy may be attributed to another sound—the “HU”. In the Shabd Yoga traditions, including Master Path and Eckankar and in the mystical Islamic path of Sufi, the “HU” is considered to be the highest vibratory mantra that can be sounded. Chanting the “HU” is said to lead one to transcendence—to God realization and enlightenment.
“HU” is believed to be the universal name of God, which is present in every existing language. The “HU” sound has been described as many things from the buzzing of bees to the rushing of wind to the flute of God. It is said to be present in the words we speak, in the sounds of animals; that it is the wind in the trees, the rushing of waters, the roaring of water falls, the beat of the sea against a beach—that it is everywhere, in every plane.
Like the “AH” and the “OM”, the “HU” may be perceived of as a seed syllable. Depending upon its pronunciation, it may also be perceived of as a vowel sound—the “U”. The “HU” creates extraordinary energy for balance and clearing. Many believe it activates both the heart and the crown chakras. When sounded together in a large group, it is extremely powerful and transformative.What leads to "HU"? 'HU' or Saut-E-Sarmad (Abstract Sound or "Sarmad"-meaning 'intoxication' for Sufis) or Anahatha Shabda (unlimited and unstruck sound) according to vedas.The great Sufi saint, Hazrat Inayat Khan in his "The Mysticism of Sound" states that the soul of the listener becomes the all-pervading consciousness, and his spirit becomes the battery which keeps the whole universe in motion.
Select excerpts from Hazrat Inayat Khan's sayings:
Some train themselves to hear the Saut-E-Sarmad in solitude on the seashore, on the river bank, and in the hills and dales; others attain it while sitting in the caves of mountains, or when wandering constantly through forests and deserts, keeping themselves in the wilderness apart from the haunts of men. Yogis and ascetics blow Sing (a horn) or a Shankha ( a conch shell) which awakens in them this inner tone. Dervishes play Nai or Algosa (a double flute) for the same purpose. The bells and gongs in the churches and temples are meant to suggest to the thinker the same sacred sound, and thus lead him towards the inner life.
This sound develops through ten different aspects because of its manifestation through ten different tubes of the body; its sound like thunder, the roaring of the sea, the jingling of bells, running water, the buzzing of bees, the tweeting of sparrows, the Veena, the whistle, or the sound of Shankha until it finally becomes "HU", the most sacred of all sounds!
This sound "Hu", is the beginning and end of all sounds, be they from man, bird, beast, or thing. A careful study ill prove this fact, which can be realised by listening to the sound of the steam engine or of a mill, while the echo of bells and gongs gives a typical illustration of the sound "Hu".
In English the word 'human' explains two facts which is characteristic of humanity: 'Hu' means God and 'man' means mind, which word comes from the Sanskrit 'Mana'( mind being that of the ordinary man). "Human" therefore may be said to mean God-conscious, God-realised or God-man.In Hindi the word "Hum" means I or we, both of the words signifying ego. The sound "Hu" becomes limited in the word "Hum" for the letter "m" closes the lips. The word "Hamsa" is the sacred word of the yogis which illumines the ego (the Hindi "Hum") with the light of reality. The word "Huma" in the Persian language stands for a fabulous bird. There is a belief that if a Huma bird sits for a moment on the head of anybody it is sign that he will become a king. It is said in the old traditions that the Zoroaster was born of a Huma tree. This explains the words in the bible, "Except a man be born of water and the Spirit, he cannot enter the Kingdom of God.' In the word "Huma", Hu represents spirit, and the word 'Mah' in Arabic means water.
'Hur' in Arabic means beauties of the Heaven, which means Heavenly Beauty. 'Zuhur' in Arabic means manifestation, especially that of God in nature. 'Ahura Mazda'is the name of God known to Zoroastrians. The first word 'Ahura' suggests 'Hu', upon which the whole name is built. The word 'Huwal' suggests the idea of Omnipresence, and 'Huvva' is the origin of Eve, which is symbolic of manifestation; as Adam is symbolic of life (like 'Prakrithi' and 'Purusha' of Sanskrit). All these examples signify the origin of God in the word 'Hu'.
'Jehova' was originally 'Yahuva', 'Ya' suggesting the word 'Oh' and 'Hu' standing for God, while the 'A' represents manifestation. 'Hu' is the origin of sound, but when the sound first takes shape on the external plane, it becomes 'A', therefore 'alif' or 'alpha' is considered to be the first expression of 'Hu', the original word. The Sanskrit alphabet as well as that of most other languages begins with the letter 'A', as does the name of God in several tongues. The letter 'A' is pronounced without the help of the teeth or tongue, and in Sanskrit 'A' always means without.
The words 'Om', 'Omen', 'Amen', 'Ameen', which are spoken in all houses of prayer, are of the same origin; 'A' is the commencement of the word expresses the beginning, and 'M' in the midst signifies end; 'N' the final word is the re-echo of 'M', for 'M' naturally ends in a nasal sound, the producing of which signifies life.
In the word 'Ahud' which means God, the only Being, two meanings are involved in assonance.'A' in Sanskrit means without, and 'Hudd' in Arabic means limitation. Hazrat Inayat Khan quotes Sharif, "I by the light of soul realize that the beauty of the Heavens and the grandeur of the earth are the echo of Thy magic flute (abstract sound)"!
