The path of knowledgeis formed by Ailm, Onn, Úr, Eadhadh and Iodhadh. Again these are trees with strong connection to the other world. The path starts with having an overview of the situation and knowing the barriers and ends with the ultimate truth and resurection. The western path is often associated with the fall, and can therefor be seen as the period in which the barrier is most clear. Maybe in the year, maybe in ones life, the fall stands for the final frontier. But it is also a signal it does not end here.
