Dharma Artha Kama Moksha - Devdutt Pattanaik

Artha-shastra is about generating food, i.e. wealth, by creating goods and services; Kama-shastra is about indulging our hungers with this food. Dharma-shastra insists we consider the hunger of others, while Moksha-shastra is about outgrowing our hungers, in order to be detached and generous. Together, these four Hindu shastras provide a framework within which human action, its purposes and consequences, can be defined; together, they validate human existence and give it meaning.
