2.  On the Kabalistic Tree of Life, eight is the number of Hod, the lowest sephirah on the left-hand pillar, the third from the top of that pillar. Hod, and therefore eight, is considered by some to be the most "unbalanced" of the Sephiroth. However, being unbalanced can be a good thing as you eventually have to move. Many consider that to be far better than being stuck in an undesired place in your life.
