“Ivy reminds us of the movement of the heavens and the way this is reflected on the earth.  It has the ability to bind all things together.  It can wander freely, linking tree to tree, or form dense thickets that block out the light and restrict passage.  Ivy brings shelter or overwhelming darkness and reminds us that where there is life, there is also death.  Ivy represents the wandering of the soul in its search for enlightenment and it carries a warning to be sure of the direction of your desires so that you avoid being ensnared by them.  True progress is made,  however, when  all the lessons of the preceding trees have been linked together with Ivy, in such a way that the light can still enter and no limb need break.”
