His mouth became the Brahmin, his two arms were made into the Kshatriya, his two thighs the Vaishyas, from his two feet the Shudra was born. So this section gives a divine explanation for the caste system. Brahmins, who as Purusha's mouth, speak to the gods, were at the top. Kshatriyas, from Purusha's arm, became the warriors, as you no doubt know, if you've ever attended my gun show. Vaishyas, the merchants and artisans who provide money for the priests and the warriors, came from Purusha's thighs. Because everybody knows the thighs are the money makers and the Shudras are at the bottom. They're the feet, the laborers and the farmers, who are the foundation of the social order.
