Nothing is eternal. Only that which dwells outside the realm of reason is forever eternal.
No, it isn't "God" but it is what it is that is so often misinterpreted by so many as "God". ""God" is just another thing we've created to try to make the unfathomable fathomable.
So is Tao. So is Brahman. So is Allah. So is YHWH/Yahweh.
These are just constructs for our limited perceptions and ignorance; for our need for words.
Because nothing is eternal, everything is sacred. Divine. Holy. Transient and shifting.
Not in a dogma sort of way, for that diminishes the possibilities. More of a dynamic spiritualism kind of way. Forever changing, recycling, pulling and pushing. Like water, or good music.
There is peace in this existence. You've just gotta learn to allow it to embrace you.
The more you deny, the less you experience.
God is a concept. The same sort of concept as the Tao. A name for the nameless. The origin. The ineffable, unfathomable, numinous-ness of our reality. Also, I notice that if one writes about "God", suddenly everyone has something to say.
