With the desire of creating the world, Brahma produced different kinds of human beings from his different organs. Thus, from his mouth, Brahmins appeared. Kshatriyas appeared from his chest, Vaishyas from his thighs and from his feet, Shudras appeared. Thus, physical body is the greatest means for human beings in order to achieve his goals. With time, the human beings lost their divine virtues and perfections. Jealousy, sorrow, decay and infighting began to rise among the people. In order to earn their livelihood and run their life peacefully, the human beings developed agriculture and other handicrafts.
“O sage! Paddy, barley, wheat, lesser cereals, sesame, millet, rice, peas, pulses, beans, rye, gram flour and hemp are common agricultural produce that have edible as well as medicinal values in the villages. These and other produce are also used as oblations in the Yagyas because all of them have produced as a result of Yagyas. Performing Yagyas daily is the most virtuous exercise that every human being should undertake. This destroys the sins committed by common people.”
