“In modern society there is always a great quarrel between the laborers and the capitalists. This quarrel has taken an international shape, and the world is in danger. Men face one another in enmity and snarl just like cats and dogs. Śrī Īśopaniṣad cannot give advice to the cats and dogs, but it can deliver the message of Godhead to man through the bona fide ācāryas (holy teachers).
The human race should take the Vedic wisdom of Śrī Īśopaniṣad and not quarrel over material possessions. One must be satisfied with whatever privileges are given to him by the mercy of the Lord. There can be no peace if the communists or capitalists or any other party claims proprietorship over the resources of nature, which are entirely the property of the Lord. The capitalists cannot curb the communists simply by political maneuvering, nor can the communists defeat the capitalists simply by fighting for stolen bread.
If they do not recognize the proprietorship of the Supreme Personality of Godhead, all the property they claim to be their own is stolen. Consequently they will be liable to punishment by the laws of nature. Nuclear bombs are in the hands of both communists and capitalists, and if both do not recognize the proprietorship of the Supreme Lord, it is certain that these bombs will ultimately ruin both parties. Thus in order to save themselves and bring peace to the world, both parties must follow the instructions of Śrī Īśopaniṣad.”
