All Vedic civilization is summarized in this verse: all living entities, either on this planet or on other planets, have to satisfy the Supreme Personality of Godhead by their respective duties. When He is satisfied, all necessities of life are automatically supplied. In the Vedas it is also stated: eko bahūnāṁ yo vidadhāti kāmān (Kaṭha Upaniṣad 2.2.13). From the Vedas we understand that He is supplying everyone's necessities, and we can actually see that the lower animals, the birds and the bees, have no business or profession, yet they are not dying for want of food. They are all living in nature's way, and they all have the necessities of life provided—namely eating, sleeping, mating and defending.
Human society, however, has artificially created a type of civilization which makes one forgetful of his relationship with the Supreme Personality of Godhead. Modern society even enables one to forget the Supreme Personality of Godhead's grace and mercy. Consequently modern civilized man is always unhappy and in need of things. People do not know that the ultimate goal of life is to approach Lord Viṣṇu and satisfy Him. They have taken this materialistic way of life as everything and have become captivated by materialistic activities. Indeed, their leaders are always encouraging them to follow this path, and the general populace, being ignorant of the laws of God, are following their blind leaders down the path of unhappiness. In order to rectify this world situation, all people should be trained in Kṛṣṇa consciousness and act in accordance with the varṇāśrama system. The state should also see that the people are engaged in satisfying the Supreme Personality of Godhead. This is the primary duty of the state. The Kṛṣṇa consciousness movement was started to convince the general populace to adopt the best process by which to satisfy the Supreme Personality of Godhead and thus solve all problems.
