Dr.Max Mueller states: "The three occupations of the Aryas in India were fighting, cultivating the soil and worshipping the gods.

Those who fought the battles of the people would naturally acquire influence and rank, and their leaders appear in the Veda as Rajas or kings.

Those who did not share in the fighting would occupy a more humble position; they were called Vish, Vaishyas or householders, and would no doubt have to contribute towards the maintenance of the armies.

[33] According to Manu, God ordained the tending of cattle, giving alms, sacrifice, study, trade, usury, and also agriculture for a Vaishya." [34] The Sutras state that agriculture, the keeping of cattle, and engaging in merchandise, as well as learning the Vedas, sacrificing for himself and giving alms, are the duties of a Vaishya.

[35] In the Mahabharata it is laid down that the Vaishyas should devote themselves to agriculture, the keeping of cattle and liberality.
