Oeaohoo

Oeaohoo is a term used in The Secret Doctrine to refer to the Logos, or more rarely to the Absolute. As the process of manifestation takes place, this principle is referred in different ways. It is also said to be a word of power. Permutations and alternative spellings include Oi-Ha-Hou, Oeaihu, or Oeaihwu.

The root of existence

According to Mme. Blavatsky Oeaohoo can be interpreted as the root of all things:

OEAOHOO is rendered “Father-Mother of the Gods” in the Commentaries, or the SIX IN ONE, or the septenary root from which all proceeds.

In one sense, Oeaohoo is the “Rootless Root of All”; hence, one with Parabrahmam; in another sense it is a name for the manifested ONE LIFE, the Eternal living Unity.

The Logoi

Oeaohoo is also made to represent the different Logoi as the process of manifestation goes on.

In the Stanzas of Dzyan the reference to Oeaohoo is mainly as the manifested logos (the third, or second, according to the numeration adopted). In this application he is called Oeaohoo, "The Younger", the "Bright Space". He is the result of the "ray" that comes from the First Logos and fecundates "the germ":

“Bright Space, son of dark Space,” corresponds to the Ray dropped at the first thrill of the new “Dawn” into the great Cosmic depths, from which it re-emerges differentiated as Oeaohoo the younger, (the “new LIFE”), to become, to the end of the life-cycle, the germ of all things. He is “the Incorporeal man who contains in himself the divine Idea,”—the generator of Light and Life, to use an expression of Philo Judæus. He is called the “Blazing Dragon of Wisdom,” because, firstly, he is that which the Greek philosophers called the Logos, the Verbum of the Thought Divine; and secondly, because in Esoteric philosophy this first manifestation, being the synthesis or the aggregate of Universal Wisdom, Oeaohoo, “the Son of the Son,” contains in himself the Seven Creative Hosts (The Sephiroth), and is thus the essence of manifested Wisdom. “He who bathes in the light of Oeaohoo will never be deceived by the veil of Mâyâ.”

Oeaohoo the younger is compared with the Buddhist concept of Kwan-Shai-Yin or Avalokitêshvara

Oi-Ha-Hou

The term "Oi-Ha-Hou" is said to be the permutation of Oeaohoo. It is used in the context of the manifestation of the hierarchies of Dhyan Chohans, "The Army of the Voice". Regarding this term, Mme. Blavatsky says:

The literal signification of the word is, among the Eastern Occultists of the North, a circular wind, whirlwind; but in this instance, it is a term to denote the ceaseless and eternal Cosmic Motion: or rather the Force that moves it, which Force is tacitly accepted as the Deity but never named. It is the eternal Karana, the ever-acting Cause.

In Stanza IV.5 Oi-Ha-Hou (or Oeaohoo in a different version) is made to mean:

“Darkness” the boundless, or the no-number, Adi-Nidana Svabhavat: —

i. The Adi-Sanat, the number, for he is one.
ii. The voice of the Lord Svabhavat, the numbers, for he is one and nine.
iii. The “formless square.”

And these three enclosed within the (boundless circle) are the sacred four.

This can be interpreted to represent the higher Tetraktys that includes the unmanifested Logos (Adi-Sanat), the manifested Logos ("the voice") and the primordial matter ("formless square"), enclosed in Parabrahman (the boundless circle).

Seven-vowelled name

Mme. Blavatsky states that Oeaohoo is a septenary name, a sound of power. It can be pronounced in different ways:

All depends upon the accent given to these seven vowels, which may be pronounced as one, three, or even seven syllables by adding an e after the letter “o.” This mystic name is given out, because without a thorough mastery of the triple pronunciation it remains for ever ineffectual.

In The Theosophical Glossary Mme. Blavatsky writes:

Oeaihu, or Oeaihwu. The manner of pronunciation depends on the accent. This is an esoteric term for the six in one or the mystic seven. The occult name for the “seven vowelled” ever-present manifestation of the Universal Principle.

These different pronunciations also refer to the different Logoi:

The One, Three, and Seven-syllabled Oeaohoo of the Archaic doctrine; i.e., the One Unmanifested Logos, the Second manifested, the triangle concreting into the Quaternary or Tetragrammaton, and the days of the latter on the material plane.”
