The astronaut's, I have no idea, I think it's just his own realizations based upon his experience. Mine? What I see as universal truth at the core of most all religious and spiritual traditions. Much from what I've learned through my own life experience and spiritual journey.
A combination of Christian mystic, ancient Essenes, Native American, Eastern oneness and the channeled material known as the Law of One mostly, a little Buddhist influence. Those are the ones which have most influenced my personal spiritual philosophy. I follow the teachings of Jesus, but not as interpreted by organized Christianity. Have absorbed much knowledge from eastern masters and yogis coming from the Hindu tradition, and integrated some of the principles of the Law of One into my beliefs in recent years.
