[36] In the same work the god Vayu says to Bhishma: "And it was Brahma's ordinance that the Vaishya should sustain the three castes (Brahman, Kshatriya and Vaishya) with money and corn; and that the Sudra should serve them." [37] In a list of classes or occupations given in the White Yajur-Veda, and apparently referring to a comparatively advanced state of Hindu society, tillage is laid down as the calling of the Vaishya, and he is distinguished from the Vani or merchant, whose occupation is trade or weighing.

[38] Manu states that a Brahman should swear by truth; a Kshatriya by his steed and his weapons; a Vaishya by his cows, his seed and his gold; and a Sudra by all wicked deeds.

[39] Yellow is the colour of the Vaishya, and it must apparently be taken from the yellow corn, and the yellow colour of _ghi_ or butter, the principal product of the sacred cow; yellow is also the colour of the sacred metal gold, but there can scarcely have been sufficient gold in the hands of the body of the people in those early times to enable it to be especially associated with them.

The Vaishyas were thus, as is shown by the above evidence, the main body of the people referred to in the Vedic hymns.

When these settled down into villages the Vaishyas became the householders and cultivators, among whom the village lands were divided; the Sudras or indigenous tribes, who also lived in the villages or in hamlets adjoining them, were labourers and given all the most disagreeable tasks in the village community, as is the case with the impure castes at present.
