Thank you very much on all these links, folks.
Brad, I *don't* mind. Most of what we call "numbers" are a positive and negative vibrational states / meanings (together with colors and musical tones) of a kind of a essentially crude but effective programming language / code in which our world is "writen".
Most vibrations have a positive and negative state - like some kind of particles, which probably actually is the case - but most of them tend to come, have an affinity to appear in their natural or prevalent state which we, unable to percieve the true energetic nature of the matrix virtual reality / maya in we are presently "submerged", interpert as "meanings".
The number 48 (much like the 13) has an extremely negative influence / "meaning".
It comprises of a 4 (negative meaning sorrow, unhappy events / positive meaning love, happinnes, golden light) and an 8 (positive: deep peace and harmony, bliss, material happiness and fulfillment in a positive sense, blue light / negative: desperation, desolation, breakdown, general cathastrophe or simply impending doom), which when added together give the vibration of 12.
The 12 is the Great Teacher, you could say that in a sense it is the symbol of this world, or the incarnation experience... Translated into words it means "the-beginning-of-strife" when it shows it's negative face / polarity, or "the-beginning-of-teaching" (you being the teacher, or being thought to, depending on the circuimstance) in it's positive meaning.
Although in 90% of cases when it appears the vibration 48 or the 8 as a single digit inalmost always acts as a "messenger of doom".
84 is usually the "happy" variant of the same thing. There's a chinese or japanese sign (can't remember now how those things are called!) which means exactly that - "harmonygold" and it's considered to bring much good luck if you as the name of your, say, bussiness.
The messenger of doom thing is specially apparent in, say, people's cell phone and credit card numbers, as well as the plates on their cars - for instance, if you pay attention to this over the years, so many times in car crashes you'll find a 0, 2, 8, 12 13 or a 48/84 in the sequence of numbers and letters on their car's plates...
I tend to think of the 48 in positive terms of gold / harmony, because that's the ideal I'm trying to achieve, the person who I'm striving to become. I was born on august 4th and you could say, in a sense that 48 is the vibration that, in short, describes tha nature of my life/destiny in this life cycle.
Hope this helps...
