Without truth there is no kindness; without kindness the truth cannot be told.
And why call ye me, Lord, Lord, and do not the things which I say? Whosoever cometh to me, and heareth my sayings, and doeth them, I will shew you to whom he is like: He is like a man which built an house, and digged deep, and laid the foundation on a rock: and when the flood arose, the stream beat vehemently upon that house and could not shake it: for it was founded upon a rock. But he that heareth, and doeth not, is like a man that without a foundation built an house upon the earth; against which the stream did beat vehemently, and immediately it fell; and the ruin of that house was great.
— Luke 6:46-49
Always respond to hatred with kindness. The most difficult enterprises are easiest at their inception, and the greatest of enterprises have humble origins. Confront difficulties while they are still easy, then, and tackle a big thing when it is still small.
There are two paths which lead to virtue: the first is to be truthful and just, and the second is to do no evil to living beings.
Disguising yourself as a kind person is even worse than being nakedly evil.
