Never have anything to do ...

Never have anything to do with likes and dislikes. The absence of what one likes is painful, as is the presence of what one dislikes. Therefore don\'t take a liking to anything. To lose what one likes is hard, but there are no bonds for those who have no likes and dislikes. From preference arises sorrow, from preference arises fear, but he who is freed from preference has no sorrow and certainly no fear.

Quotes from the same author

Those who attempt to conquer hatred by hatred are like warriors who take weapons to overcome others who bear arms. This does not end hatred, but gives it room to grow. But, ancient wisdom has advocated a different timeless strategy to overcome hatred. This eternal wisdom is to meet hatred with non-hatred. The method of trying to conquer hatred through hatred never succeeds in overcoming hatred. But, the method of overcoming hatred through non-hatred is eternally effective. That is why that method is described as eternal wisdom.
If one man kills a hundred men, and another man masters himself, the second man is the much greater warrior.
The no-mind not-thinks no-thoughts about no-things.
A wise man, recognizing that the world is but an illusion, does not act as if it is real, so he escapes the suffering.
Like the mother of the world, touch each being as your beloved child.
