an early Upanishad, Shudra is referred to as Pūşan or nourisher, suggesting that Shudras were the tillers of the soil. But soon afterwards, Shudras are not counted among the tax-payers and they are said to be given away along with the land when it is gifted. The majority of the artisans were also reduced to the position of Shudras, but there is no contempt indicated for their work. The Brahmins and the Kshatriyas are given a special position in the rituals, distinguishing them from both the Vaishyas and the Shudras. The Vaishya is said to be "oppressed at will" and the Shudra "beaten at will." Second urbanisation (500–200 BCE) Knowledge of this period is supplemented by Pali Buddhist texts. Whereas the Brahmanical texts speak of the four-fold varna system, the Buddhist texts present an alternative picture of the society, stratified along the lines of jati, kula and occupation. It is likely that the varna system, while being a part of the Brahmanical ideology, was not practically operative in the society. In the Buddhist texts, Brahmin and Kshatriya are described as jatis rather than varnas. They were in fact the jatis of high rank. The jatis of low rank were mentioned as chandala and occupational classes like bamboo weavers, hunters, chariot-makers and sweepers. The concept of kulas was broadly similar. Along with Brahmins and Kshatriyas, a class called (literally householders, but effectively propertied classes) was also included among high kulas. The people of high were engaged in occupations of high rank, viz., agriculture, trade, cattle-keeping, computing, accounting and writing, and those of low were engaged in low-ranked occupations such as basket-weaving and sweeping. The were an economic class of land-holding agriculturists, who employed dasa-kammakaras (slaves and hired labourers) to work on the land. The were the primary taxpayers of the state. This class was apparently not defined by birth, but by individual economic growth. While there was an alignment between kulas and occupations at least at the high and low ends, there was no strict linkage between class/caste and occupation, especially among those in the middle range. Many occupations listed such as accounting and writing were not linked to jatis. Peter Masefield, in his review of caste in India, states that anyone could in principle perform any profession. The texts state that the Brahmin took food from anyone, suggesting that strictures of commensality were as yet unknown. The Nikaya texts also
