Notice what God doesn’t say. He doesn’t say, “there is nothing to be afraid of.” Rather, he says “Do not be afraid.” It seems implied that there are things which will cause us fear. Jesus even asserts that, “In this world, you will have trouble.” But then he also says, “Take heart! I have overcome the world.”
What is called human attachment is really a profound idea. It’s the idea that from day one, we are all seeking connection with others, specifically “higher minds” in order to organize ourselves, feel sure of ourselves and secure.
If you think about it, nearly everything could be seen as attachment behavior. Everything is an attempt to secure our place, know we are safe, feel valued. I just remember thinking as a kid: “If someone could just notice me enough, then I would feel right.” We are built for this sort of seeking out of attention and comfort. And for me, this flows right to spirituality: the only way any of us will feel truly secure is if we find that deeper Force which caused the universe to quicken into existence.
