This date is significant because 2016, reduced Kabbalistically, is 2+0+1+6=9. That's 9-11-9. Not only does it reflect the two upright Pillars in ATTLAS, which form the gateway from where we are to where we long to be, but REVERSES the effects of 9/11. Fifteen is 1+5=6. That is the inverse of 9. So fifteen years aften 9-11 we can say that we have hot the bottom...whatever was set in motion for us, personally, on that day, this is our opportunity to comprehend it and rise back up.
