Hatred is a state of insolvency towards compassion.
One can not be hateful towards a hater, precisely for this. One has to be totally devoid of compassion, to be able to hate a hater. A hater makes one a hater. One can’t afford to be a hater, if one is not. Haters win by hatred, not by compassion. Love is the absence of cruelty. Hatred is the absence of compassion. Cruelty and hatred live together. Love and compassion live together. Live away from hatred and haters. Seek compassion and love.
