King Solomon's Cattle Spine

Origin
Scholars would argue over many things, one of these was a sensation of leaving the body when sleeping. Most pushed it off as vivid dreams however King Solomon wanted to know more about it as he was composing the book in the Bible, Ecclesiastes. His servants told him about a psychic silver cord that would allow one to traverse the heavens. Wanting to speak with the Lord about countless things Solomon put his faith into his servants to come up with an answer. Over time he came to realize that the silver cord wasn’t a link to the heavens but a metaphor for life itself. When the cord is cut meant when his life expired he would be free to return to his Lord, his body to ash, to the earth. One of his servants, while in search of these answers, sought out the spine of a cattle presenting it to him more as a reminder of the time they spent researching together. The spine became imbued with their hope and faith.
