The law of compensation operates everywhere in Nature's phenomena. The seed breaks and a big tree appears from the seed. The tree comes out in accordance with the law of compensation. Fuel burns and is destroyed. But there is heat in accordance with the law of compensation. Many articles are cooked in the fire on account of the heat. If there is extreme heat in Bezwada, there is extreme cold in Mt. Kailas or Uttarkasi in the Himalayas. This is the law of compensation. If there are ten scoundrels in a place, there are two Sattvic souls to bring compensation. If there is flood-tide at Puri, there is an ebb-tide at Waltair. This is the law of compensation. If there is day in India there is night in America. Peace follows a war and vice versa. Water becomes steam and the steam makes the engine move. The sulphuric acid in a jar of a battery is consumed but there is electricity produced in the bulb. You get light. This is the law of compensation. The law of compensation operates in the mental plane also.
Every effect has a cause. Every consequence has an antecedent. There must be perfect balance between the cause and effect, between the antecedent and consequence. The law of compensation keeps up the balance, and establishes peace, concord, equilibrium, harmony and justice in Nature. Think deeply. Reflect and cogitate. You will notice that this law of compensation is operating beautifully everywhere in the phenomena of Nature. It is inexorable and relentless. No one can defy this immutable and irresistible law. If you do an evil act, you will reap a bad fruit in compensation.
Sometimes a man complains: "God is unjust. I have always been a truthful man. I never do any wrong to anybody. I am always serving humanity. Yet I have this terrible disease, asthma." This is incorrect and unreasonable. You will have to connect the effect with the cause always. Whatever you suffer from may appear to be unjust. You may think that you do not deserve it at all. But if you try to find out the cause of this suffering, you will doubtless find that it is perfectly right and a just compensation. Then you will have satisfaction. Just try in a few cases. Then you will have no room for complaint or lamentation. You will understand the beautiful working of the law of compensation. The affairs of our lives are so very intricate and complicated that we find it difficult to trace the cause of the present suffering. Though we are not able to trace the cause, though we are not able to understand the working of the law, yet the cause is there. Our intellect is so feeble that it is not able to grasp the antecedent or cause of a suffering or event.
