The holy girdle, the common symbol of the Dvija as opposed to the Çudra, must consist with the Brahmans of three threads of cotton, with the Kshatriyas of three threads of hemp, with the Vaiçyas of three threads of sheep's wool. The Brahman wears a belt of sugar-cane, and carries a bamboo staff; the Kshatriya has a belt of bow-strings, and a staff of banana-wood; the Vaiçya a girdle of hemp, and a staff of fig-wood. The staff of the Brahman reaches to his hair, that of the Kshatriya to the brow, that of the Vaiçya to the tip of his nose. This staff must be covered with the bark, must be straight, pleasing to the eye, and have nothing terrifying about it. The Brahman wears a shirt of fine hemp, and as a mantle the skin of the gazelle; the Kshatriya a shirt of linen, and the skin of a deer as a cloak; the Vaiçya a woollen shirt, and a goat-skin. Any one who is inclined to do a civility, must, says the book, ask the Brahman whether he is advancing in sanctity, the Kshatriya whether he suffers in his wounds, the Vaiçya whether his property is thriving, the Çudra whether he is in health.[296] We cannot exactly ascertain what position the old nobility, the Kshatriyas, took up after the establishment of the new system. The increased power of the kings, the elevation of the priesthood, the change in the whole view of life, diminished their importance to a considerable degree. If in some small tribes the warlike nobility on the Ganges maintained its old position so far as to prevent the establishment of the monarchy, or removed it altogether, this was an exception.[297] In the Panjab, which did not completely follow the development achieved in the regions on the Ganges, it was more generally the case that the nobility overpowered the monarchy, and drove out the old princes. This took place, no doubt, when the latter showed a desire to take up a despotic position. In the fourth century we find among "the free Indians," as the Greeks call them, numerous noble families in a prominent position. The book of the law allows that the Brahmans cannot exist without the Kshatriyas, but neither could the Kshatriyas without the Brahmans; salvation is only to be obtained by a union of the two orders: by this were Brahmans and Kshatriyas exalted in this world and the next.[298] We have already remarked, that within their own caste the old families of the Kshatriyas occupy a prominent place.
