If I do not love myself, I cannot love others also. If we really love ourselves, we cannot think wrongly, cannot talk wrongly, cannot act wrongly. If you know how to love yourself, then you do not bring hatred anywhere. Mind is the forerunner of all good and evil. When mind becomes purified, it creates good karma. When mind is nonpolluted, then your action will be pure, the world will be pure. When you talk, it will be wise, nice, friendly. If you do not understand your anger and mind is influenced by anger, it becomes poisonous, and you suffer physically. When you act, it will create tension. It is the same for everybody.
Mettā brings loving-kindness, makes you healthy. If you do anything good for others, it is good for you. Hatred never ceases through hatred in this world. Through love alone it ceases. This is an eternal law. There is no American love, Indian love–no difference. The mind is a wonderful force. Pervade your whole being with loving thoughts, from your pure heart. If you love your enemies, you will have no enemies. This is the only way, so you can be helpful to the universe.
