Nothing is simpler than love.

Nothing is simpler for man than the act of love, which in this case can indeed dispense with every precaution and care since the self-surrender to the person one adores is at the same time self-surrender to the promise of eternal bliss and, as such, is an act which could never be surpassed by a greater or a better. When one's beloved is none other than God, the ego's experience of losing the ground under its feet as a result of genuine love is none other than the beatific shudder of self-surrender which every believer is basically disposed to experience and which the mystic actually experiences already here on earth.

—Hans Urs von Balthasar, The Glory of the Lord, Vol. 1: Seeing the Form (1961)
