That is why right, temporarily defeated, is stronger than evil triumphant. He who is devoid of the power to forgive is devoid of the power to love.

It is impractical because it is a descending spiral ending in destruction for all.

If you close your mind with judgements or traffic with desires, your heart will be troubled. If you keep your mind from judging and aren't led by your senses, your heart will find peace. Seeing through darkness is clarity. Knowing how to yield is strength. Use your own light and return to the Source of light.
