OM = AUM, everything, source, vibration, consciousness of whole universe, infinite, absolute, opposite of Maya(illusion, world), …

Here is some explanation for you and maybe other members can add, especially from Arabic meaning. Online ‘The Om symbol is a combination of curves, a crescent and a dot. The meaning of the Om symbol, while purely looking at its visual form, comes from the states of consciousness that Aum represents. The letter ‘A’ represents the waking state, ‘U’ represents the dream state and ‘M’ is the unconscious state, or state of deep sleep.

In the symbol, the waking state is represented by the bottom curve, the dream state is the middle curve and the state of deep sleep is represented with the upper curve. The crescent shape above the curves denotes Maya, or Illusion, which is the obstacle that sits in the way of reaching the highest state of bliss. The dot at the top of the symbol represents the absolute state, which is the fourth state of absolute peace and bliss, that is only one state actually. ‘ Yod from Hebrew would definitely be similar to the dot, which is the ‘I’ name of God as also explained by Rupert Spira, and crescent moon has definite meaning in Hebrew and all esoteric traditions and relates to evolution of consciousness. Hope I was able to help a bit. Anna Bharati Wysocka

Anna you covered the most commen in your comment.
The symbol is the first letter in Sanskrit = A.(A is build of 3 lines or I’s.(I-I)
The part 3 from the symbol is the number 3 and means 3.
Its the same as the trinity in Christianity.
Father, son and holy spirit.
Brahma, Vishnu and Shiva.
All there is…
First dot were all is coming from.
Half circle can be the circle of ring pass not the second.( hidden part)
And then the 3.
Creation…
Its first sound from the new bourn when it comes out from the mother screaming aaa, auuu and ending aummm.
First is birth, second withholding (continuing)and third destruction.
Out breath, pause and in breath then a knew pause that compleat the round. (fourth).
The tail on the 3 that becomes a circle is not always a circle but is included as a tail in the number 3 in Sanskrit.
Often its just a tail(snake, continuous.
But as circle a conclusion of all.
Included in the dot is the the 3 from previous round as its always this 3 that are and it becomes the 3 again…
a little on the subject!

Robin Starbuck I think you can see the link the tail.
Arabic is one of the oldest writhen language.
All languages come as symbols from sound.
Hinduism and Islam are living close and Islam and Christianity are bourn from the same.
Before it become language it was pictures symbols and that become letters and words.
9 is a deep symbol in it self as number nine then as snake, boat, link, spiral, broken circle and circle, nr of initiations to fulfilment, 3×3….
Arabs used it alot as boat(link),snake in there old language and in the Om symbol we can also se it as a link to the new dot a new birth a new round…or just as all there is and will always be in continuum…
So when it become letters and words all languages are conected by symbols,words, sounds that they got from each other and mixed in to there own.

love and light🌟
