Very interesting discussion and many interesting points! I will only speak for myself and the wisdom that I have found in my short life.
This is my truth and understanding.
I have always have a love and amazement for nature since I was a boy.I always returned to a special place in Kangaroo Valley, a pocket of Rainforest,a meeting of 2 rivers on,"flat rock".Before I started my HSC exams and when I finished,before the start of a new career and at the end of one,when I have relationship issues and need clarity and at the ending of a relationship or friendship.What I' trying to saying a long winded way is that nature has always been my guide and comforter at many junctions of my life and continues to be so.
Through nurturing nature through agriculture and many other ways, I have learnt many things and the concept of cyclic regeneration of the souls of nature has become intrinsic to my worldfeeling and worldview that reincarnation has become a given.
To me,being Pagan leads to a belief in reincarnation into other worlds,under and upper worlds.
It's a funny sort of question to me really,no offense, but it's like a Christian asking if they can be a Christian even if they don't believe in heaven and hell!
