From what I got this universe or octave of reality has 12 densities or vibratory levels. The 13th level is part of this but sticks out because it is like the sum of the (12) parts. Some call this level the Christed state of consciousness. The 13 can also be seen as the center of a wheel having 12 spokes.
Now, these 12 densities have 12 sub harmonics so 12 times 12 is 144. So thats just for our local universe, cause beyond this the vibratory levels keep rising up toward oneness of god. From here to full oneness there are many levels. tho each soul carries that intense spark of oneness inside. 144 can also be found in the new energy grid that has been build and prepared for since the fall of Atlantis. A Grid that is composed of 144 key points, Ley-line crossroads of telluric energy which are directly linked with consciousness. consciousness, grids, energy and geometry are directly associated. This crop circle represents the 144 folded /pointed grid. The builders of ancient sites, temples and pyramids have somehow kept going this titan project over the years and from good source I know that this grid is ready and ready to hold our new consciousness into form and our planet. Hope this inspires ; )
Ah yes, ps : There are also 144 moon combinations as there are 12 zodiacal signs and 12 constellations in which your moon can be located in your birth chart as shown on this page : http://www.astrology-numerology.com/sun-moon.html
