OM written in Devanagari as ॐ
OM or Aum (in romanized script) symbolizes the energy emanation from the One, which we understand as the Divine vibration (Force or Energy or Sound) that creates and upholds all in the universes, the Life Force, the Presence of the Benevolent Divine among us, The Way.
That flow of Divine Energy is The Way. Wayism is rooted in this understanding of the Divine presence and its Flow, the Divine Plan for the universe(s), and we endeavour to flow along in that river of energy to fulfill the purpose of our lives.
Aum or OM is just a symbol that points to something. It holds no magic, no super powers, unless you make it so. Wayists make it so. For us, there is no greater consciousness but The Way. Reading our primary Scripture, chapter The One, devotees learn that Wayists do not speak of the ineffable One, the Tau, because we cannot, so we don't. The best that we human souls and body-minds can attain to is to experience or sense The Way flowing throughout all, and that is Aum or The Way, symbolized by ॐ
Aum is a symbol for the Almighty One
This brings us to Namaste
Iesous worked in the east for many years before He ended the human incarnation phase in Israel. Iesous made liberal use of the Aum symbol and practice to attune himself when he delivered teaching. The word amen derives from Semitic languages and means righteous, true and/or steadfast, it is used about 30 times throughout the Old Testament. In the New Testament, Iesous is quoted using the symbol more than 50 times in one Gospel and almost as frequently in the other Gospels. Iesous also used the symbol differently than it was traditionally used in the Old Testament. Most of the time He is qouted using Aum as an attuning, before he said the words.
This brings us to the Namaste. Iesous and Mari, coming west after many years in the east, introduced to westerners the then foreign concept of holding the hands together as a form of respectful supplication to the indwelling spirit of the other person. To greet in this respectful eastern manner became a thing that people of the Way did. In the mid-east it was later associated with the people of the Way. Christianity, however does not believe in the indwelling spirit as we do and therefore reserved the Namaste only for use in prayer when addressing God.
