Well, after reading that I'm going to have to admit that I, too, agreed with that definition at one time. But it's certainly not a label I hold any longer. I think I held this opinion then in the hopes that if there really were a god, I might still get points for the effort of calling myself something closely resembling what he/she wanted me to be.
I understand now am I not spiritual as described in the definition above, but really only a human being who wants to do the best I can during my short stint on this planet. I'll agree (slightly and with some modifications) that I have "a sense of purpose in life and a quest for meaning, acceptance of the sacredness of nature and of all human experience, knowledge that ultimate fulfillment is found in
So, I'm not spiritual, but I am a good human and I'm self-led. And that's about as deep as it gets.
