Next time, use periods instead of spaces when making things that need shape like that. I learned that the hard way too a while back.
Great topic idea!
"Agla" is a condensed power word for the hebrew god, "Atah givur l'olam, adonai." You are great forever, my Lord"
We can create our own words like this in any language, and people do it all the time. For instance s.w.a.t. team, s.c.u.b.a. diver, n.a.s.a., etc. These are new words created from full phrase descriptions. So you can create your own phrase, condense it to initials and write it/say it and no one but yourself and those you tell will know its meaning. Neat trick for those in the broom closet. ;-)
"Aum" known as "Om" is very well known. Try sitting up straight and saying "ah", drop the note until you feel it in your hips, drop it lower until you feel it under your hips...ah, the root chakra! Now from "ah" change the sound to a "o" sound like in "foot". Play with the note of it until you feel it in your belly and chest. Finally "mmm" until it feels like its circling your head. Now THAT'S how you really use the power of "Om"!
