From his eyes came the sun, his mind the moon, his breath the wind, and all other parts of the universe. The distribution of body parts from the cosmic man or "Purusa" gave birth to not only the universe, but also meaning to each caste. The Brahmans, which were birthed from the mouth of Purusa, were the priests of Hindu religion. The Kshatriya were the warriors made from the arms. The Vaishya were workers coming from the thighs and the Sudras were servants made from Purusa's feet. .
The Laws of Manu and Bhagavad-Gita emphasized the importance of each caste systems roles and duties. Both texts state that if people ignore their sacred duty the world will fall into chaos and society will crumble. They also state that you can only reach the final goal of the religious path ( Moksha ) in an ordered universe. The ideal life of a Hindu begins with the learning of their caste in which they were born into. They Brahmans start by finding a spiritual preceptor called a Guru in which to learn their social class roles from. The three highest castes, which consist of the Brahmins, Kshatriyas, and the Vaishayas, are said to be "twice-born" and the only castes able to witness the sacrifice rituals and practice the Vedas. These castes are said to have been "twice-born" because they go through a ceremony called Upanayana, which initiates them into adulthood.
The Brahmins were the only caste system able to learn and teach the Vedas. The Vedic texts the Brahmins taught were not to be written down and strictly guarded from other castes. The Rajanya ("royal") class was the kings and rulers, later called the Kshatriyas. Kshatriyas were able to learn the Vedas but could not teach them. Their Dharma was to protect the people and the country. The kings were to conquer their senses. He is to get rid of the vices of pleasure, such as hunting, gambling, drinking, and obsession with women. Kings were also to avoid violence, envy, slander, unjust seizure of property, and assault.
