Srila Gurudeva Bhaktivedanta Narayana Goswami Maharaja
"In this world, it is absurd to think one can love all living beings. If you try to love a ferocious tiger, for example, he will attack you. A poisonous snake may attack and bite you if you try to show it love. However, if you can love the Supreme Lord, that love will be distributed to all beings, and all can be happy. This is the true 'love and affection theory.'"
