By hating that person, you have lost something very sweet in yourself.
You hate someone whom you really wish to love, but whom you cannot love. Perhaps he himself prevents you. That is a disguised form of love.
Ignorance is an enemy, even to its owner. Knowledge is a friend, even to its hater. Ignorance hates knowledge because it is too pure. Knowledge fears ignorance because it is too sure.
Silence tells the seeker in us to love, to love himself. It tells us it is wrong to hate ourselves because of our imperfections. When the seeker loves himself, loves the Divine within himself, he eventually realises the Ultimate Truth.
Hatred is a disguised form of love. You can only hate someone whom you really wish to love, because if you were totally indifferent to that person, you could not even get up enough energy to hate him.
We must see that God operates not only in us but in others as well. God also operates in our so-called enemies. But these are not our real enemies. Our real enemies are doubt, fear, anxiety and worry. When we do not cry to perfect others, but only try to perfect our own lives, then we will have joy.
