On the premise that human life is meant for spiritual progress, the Vedic literature presents as the ideal social system one that trains people, materially and spiritually, in four occupational groups and four stages of life. These occur naturally throughout the world and are not based on the family one is born into. The four occupational groups are the intellectuals, the governing/martial class, the mercantile/productive class, and the working class. And the four stages of life are student life, married/working life, retired life, and the renounced stage of life for full spiritual dedication.
When everyone is situated comfortably according to his or her unique nature, there is smooth social interaction. Members of a peaceful society can concentrate on spiritual topics, and everyone should be encouraged to perform his or her duties as an offering to God. At the heart of the Vedic social system is the principle that a peaceful, prosperous society results when people put God in the center of their lives.
The Vedic system stresses simple, thoughtful living, which includes respect and protection for each person, the environment, and all living things, in line with Krishna’s natural laws.
