Wow Dop,
I know exactly what you are talking about. The night I left my son out in the cold I actually felt something die in me.
This is how I describe it. Death is separation. Detachment is separtation. Being set apart. In religious terms I believe this is the process of sactification. When we are separated from things of the world and then joined to God instead. I think it's the timing that makes us feel so cold. Seems the separation must come first. They went through the desert before they made it to the promise land. They were separated from everything they knew and then received the promise. The land of milk and honey.
Hugs,
