OM..what does it mean?

I'm not sure if you've realized that when you ask someone the meaning of OM...you get answers like: "Universe", "past, present, and future", "what has existed, what exists and what shall exist"..the thing is that these and many other answers are all right...but in my search for the meaning of OM...i realized that it is very difficult to summarize the meaning of a symbol that is so rich in both meaning and in depth.  OM I have found is the divine that is housed inside us..how we connect with our past, our present and our future..our consciousness and connection with the divine in ourselves and in others..OM is the sound of the divine...in the past, the present and the future!
