Balance comes from an open heart that lovingly bonds thoughts with emotions. Heartlessness stems from a failure to allow thought and emotion to bond - typically thoughts reject emotions they don't like or want to listen to.

We (and God) have come a long way since the understandings present during the days that world religions took form. We do need to become divine versions of ourselves, but old world religions are not capable of that. In truth, they all contain errors which are part of what is causing the problems in the world.
