Pantheism: Pantheism is a naturalism of the divinity of Nature.
Panentheism: Panentheism is a belief system that posits that the divine exists and interpenetrates all parts of nature, but at the same time extends beyond it.
We distinguish panentheism from pantheism which holds that the divine is entirely in the universe, without being either external or superior to it.
There are two worlds: the manifested physical and the unmanifested invisible. The created and the creator. The material world and the spiritual world. The effect and its cause. It is fundamental to establish a basis of two planes, because this de facto results in two different types of realities and therefore two truths as opposed as the two planes.
This way of seeing the world may be surprising, because materialist society attempts to impose a one-dimensional world where matter is deified. And therefore it is no longer the projection of an intention, of a creative verb; but it is sufficient in itself. This is the message conveyed by the Avatar films featuring a people living in symbiosis with sacred nature and its elements. Because there is pantheism meaning that the divine is included in nature, because “the divine is everything”.
And there is panentheism which unites the divine and nature, but without confusing them. The divine is in this case distinct from creation, from Mother Earth.
In pantheism, nature is the divine. The latter is included in nature.
In panentheism, nature is the mirror of the divine. The latter is distinct from nature.
In pantheism, the creative plan and the created plan are the same thing. In panentheism, the creative plan is prior to and therefore superior to and different from the created plan. Vastly different, because the first limits the relationship with the divine in its unique physical dimension. It is a natural spirituality. There is horizontality of the sacred. The second opens the relationship to divine reality in a different and therefore higher dimension. It is a supernatural, vertical spirituality. And so the Avatar films promote the sacred in nature, through stories of people living in communion with Gaia. But this approach deprives us of a dimension of transcendence. These Avatar films well summarize the global trends of post-industrial societies and religions; those of placing the divine at the heart of nature and men. Humanism and the return to natural values place the creative plan in matter.
