In history, the development of the urban settlements was a momentous achievement. Urban life can be contrasted to rural life with the lack of dependence on agriculture and pastoralism. The word “urban” is derived from a root meaning refined or cultured.
The development of urban centers in India can be observed to be an ancient phenomenon. Buddha developed and spread his philosophy mainly in the urban centers of his day in around 500 BC. Varanasi (or Kashi), one of the most ancient cities in the world, was one such center where the Buddha taught.
The word “Sanskrit” means refined or cultured. One can thus infer a close correlation between the development of Indian urban centers and the growth of Sanskrit.
