I was a die-hard atheist before the initial awakening, and became one on my own in elementary school. God doesn’t care.
After – or within – an awakening, we tend to operate from the same general worldview as we had before the awakening, only modified some to fit our new reality. We used to be Christian, and still are afterwords. Or Muslim. Jew. Buddhist. Taoist. And so on.
And the same goes for atheism. The worldview I am most comfortable with is in many ways the worldview of an atheist, only modified to fit my new reality. I still have a more-than-average interest in science, and now also in stories about science that bridge science and spirituality such as integral views and the Universe Story. And it also means I am free to explore pointers and teachings from any tradition, and value and find appreciation for them.
Of course, this isn’t really atheism anymore in an everyday sense, but it is at least flavored by atheism. And it is atheism in a more real sense, to the extent that there is a freedom from belief in stories about God, reality, the world, myself.
