Per the responses I've received back on this post... No, I don't have any known ties to the 9/11 attacks in NYC. I was safe in Texas at the time, and I never had any friends or family who were impacted. So in my case, I don't think the 9/11 attacks are the reason for me seeing these numbers. Also, I do tend to see these numbers more as "119" than as "911". Part of that is just "gut feel," part of it is because my birthday is January 19 (1/19), and part of it is because I've seen these numbers presented as "1:19" many more times than I've seen them as "9:11". I have pursued several different possibilities regarding these numbers:
(1) I looked into the standard numerology meanings that the mainstream astrologers would attribute to the individual numbers 1, 9. and 11. I summarized that in my original post.
(2) The number 19 is associated with the Sun tarot card. A description of this card from a mainstream astrology site is "The Sun card presents an feeling of optimism and fulfillment. This card represents the dawn which follows the darkest of nights. The Sun is the source of all the life on our planet, and it represents life energy itself. There is a child depicted in the card, playing joyfully in the foreground. A symbol of our innocence, it represents the happiness that occurs when you are in alignment with your true self. The child is naked, meaning that he has absolutely nothing to hide. The card also depicts the childhood innocence and absolute purity. This is particularly emphasized through the white horse upon which the child is riding. The horse here is also a symbol of strength and nobility."
(3) A lot of mainstream astrologers talk about 19 as a "karmic debt" number. One of them describes it as follows: The number 19/1 represents wisdom, power, and spiritual knowledge that has been used and abused for selfish personal gain in a previous manifestation. If you have a 19/1 as one of your Core Numbers, understand this: You are now paying back for past abuses where sacred knowledge, lack of compassion, and spiritual misalignment were your behaviors. The 19/1 indicates to you that there has been a hefty abuse of power and that the actions involved were extremely self-centered and the abuse wasn’t willy-nilly – it was calculated. Understand that the person who has the 19/1 as one of their core numbers will most likely act upon the more destructive tendencies of the number 1 until the lessons have been understood, acknowledged, acted upon, and mastered."
(4) I looked into the possibility that maybe one of our Satanic gods was trying to contact me. I researched which god(s) were associated with my birthday of 1/19. The only one I could find was goddess Vapula. I tried communicating with her to no avail.
(5) I read a blog where they were discussing the importance of 119 to the Yehuborim and the Freemasons. They claimed the following phrases all have gematria values of 119: "Zedekiah's Cave", "Master Plan", "High Priest", "King James Bible", "Star Of David", "All-Seeing Eye", "Birthright", and "Divine Rule".
(6) Also regarding gematria, the yehuborim have a perverted title for Enlil/Baal Zebul called "The Lord of the Flies," and they associate the number 119 with this.
