Just as a mother would ...

Just as a mother would protect with her life her own son, her only son, so one should cultivate an unbounded mind towards all beings, and loving-kindness towards all the world. One should cultivate an unbounded mind, above and below and across, without obstruction, without enmity, without rivalry. Standing, or going, or seated, or lying down, as long as one is free from drowsiness, one should practice this mindfulness. This, they say, is the holy state here.

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.
