Native American Spirituality deals with pantheism. If you're wanting to learn more about pantheism from a Native American point of view, you should really research the different animal spirit guides. Native Americans believe strongly that animals are gods, or ancestors. Sorry it's not much info for you, but it's a start!
Thanks, Daniella but I don't know that they consider animals as "gods", but definitely as spirit guides. Yes, I'm aware that Native American spirituality in many tribes can be related to pantheism, but I am looking for more of a modern day approach to pantheism. Thanks, though!
Pantheism is simply the belief that God is everything. You are God. I am God. The trees and air and the grass are God. The planet is God. Everything in the Universe is God. Many paths are pantheistic in nature with Wicca being the most prominent one (or at least one to point it out). However, some will argue that Wicca is not pantheistic in that some believe the Gods to be actual entities and only their essence is in all things. You can find information on one Pantheist society at http://www.pantheist.net/ They propose a way of life that is specifically pantheist going beyond the term alone. That may be more of what you are asking about.
What you describe is actually animism. In the Wakan, The Great Spirit is the supreme being and all spirit is the Great Spirit. This is the concept of Manitou, the Spirit Which Dwells in All Things. The wind is spirit, as is fire and water. The trees, flowers and rocks also harbor the spirit. Pantheistic beliefs are better defined by Egyptian, Greek, Roman and Nordic cultures. Hinduism is also based on a Pantheon.
The most beautiful expression of Pantheism I have ever read is in the Bhagavad Gita, the holy book of the Hindu. In the 6th teaching "The Man of Discipline" Krishna says; (6:30) “If you see me in all things and see all things in me, then you will never lose sight of me, and I will never lose sight of you.”
