Two years ago in my https://medium.com/know-thyself-heal-thyself/the-human-spirit-duality-e456c0729e99, I wrote:

"Recently I had this realization about the human-soul duality — the goals of the human and the goals of the soul may be, from the human perspective, irreconcilable. Humans want nothing but happiness but perhaps the soul came here to experience the opposite so that it can learn to guide other humans when it is not incarnated and is assigned as a spirit guide or to some other work in heaven."

That essay included reference to your "The Human Self and the Soul Self, Two Parts of the Same Being"
