Love is a vibration, a level of consciousness unto Itself.
In Dr. Hawkins levels-of-consciousness-map that he shares, he shows Love is a 500 level. At this level one individual counterbalances 750,000 people who function below the 200 level (the more negative vibes).

It also tested out to show this is the level, too, of song birds songs, and a cat's purr or a dog's wagging tail....can't leave our precious pets or animal kingdom out.
"The people who know God well - those who risk everything to find God - always meet a Lover, not a dictator."
