Numerologically speaking, the number 27 equates to the number 9 (2+7 = 9). The number nine is dramatic compared to other numbers. It signals change, especially since it is technically the last number, but it also means that things will begin again. It signifies adventures, extreme or subtle changes, deep thought, rebellion, death, birth, creation and destruction.
In Tarot, the number 9 represents The Hermit card. The hermit shows a time of meditation, deep thought, spiritual pursuits, truth seeking, a light in the dark... He often comes out when a big change or opportunity is coming our way, and he says we should contemplate it for a while, but not dedicate our lives to our troubles.
