Love is many a thing, from a feeling that might be selfish, to a service done in secret. Love can be the crest of an emotion, or it can be the toil of assistance.
Love can be forgiveness, or it can be judgment, a balm to soothe, or a surgical knife.
If love wore one expression, if its hands were always open, if it gave and never retained, then it could exist as a sentiment without thought. But true love places a supreme demand on the resources of wisdom, for manifestations of love are as varied as human need. It would be vice. Love must be ready to embrace or to refrain from embracing, to give or to deny. It requires expenditure and vigilance.
