The atheist, too, has a god, and it is himself.
The idolater at least understands there is something greater than him, something beyond the grasp of his physical senses, some external forces to which he is subject.
But for the atheist, all the universe is defined by his own understanding, all ethics are subject to his approval, and even he himself is an artifact of his own mind.
He is a self-made man, for he creates his own universe. But he has neither windows nor light.

Both the idolater and the atheist is, as is everyone, guided along the path he has been put on by the One Self. We all have been born into a developing narrative, or rather, a concept. These concepts are based on a narrative we each were born into, a story going back in history, a religious story, a cultural story, a family narrative which forks out into a personal narrative of “me” and “us”. We identify with our stories, and interact that way. In the end we realize that we should not identify with the body.
We are always imagining we in our bodies are in control. But we should rather be living Pure Consciousness: the True Self. That is the Oneness of G-d.
