Romance/Heart is Vibrations. Intellect/Mind is Focus.
If you just have a vibration with no focus, there's no direction. You're sympathetic and caring, but don't know quite what they want yet, like perhaps Sam (me) or BG.
If you just have focus with no vibration- you'd succeed well and naturally become an authority as you'd see the pure reality of things, but nobody would really like you. You'd be like Expat or a Freud.
To me and my natural demenaor, vibrations are more important. But we're constantly playing with the two and 'real world' and life you need both to survive.
