In Dharma Artha Kama Moksha Devdutt Pattanaik uses his unique understanding of mythology to provide an accessible and lucid guide to the Hindu way of thinking with short essays that are crisp expositions of important concepts.
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.
