I do not understand where we disagree in this particular case. I have not said that reason can fully control the underlying spheres. Those get integrated into the self with development.

Back to love. Do you think, in the case of Jesus Christ, love comes from "below," the less controllable spheres (relative to thinking individuals we are), or from "above"?

I wouldn't put it like that at all. Each stage represents both love and death, doesn't it?
