Fear IS the need when you are not love. Love is always enough when you have it, and no love is enough when you dont.
There has to be a complete committment is one's love. This has to be the case because love is action and you cannot perform half-heartedly any action. You can't half-heartedly walk across the road, not in the action of walking at least. You could say that you will not pay attention while you do it, but then that does not effect the action itself. It just means your unconscious while you do it.
