The secret of health for both mind and body is not to mourn for the past, nor to worry about the future, but to live the present moment wisely and earnestly. There are only two mistakes one can make along the road to truth; not going all the way, and not starting.
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.
