All injustice that prevails in the world is one. Because all injustice arise out of one or the other form of fear. There is no greater foe in the world than fear. In order to be free of fear a human accepts injustice. That is where evil is born. Out of fear, a human mind is filled with worry and conflict. He loses his ability to think. The mind or the soul is destroyed. Due to fear a human mind is filled with bitterness. His entire life is filled with bitterness. The joy of living is lost. Out to fear, a human drifts away from the Almighty. No power is so great that it cannot be defeated, and no injustice is so minor that it need not be defeated. Because a minor injustice with the passage of time can attain a catastrophic form.
