It is necessary to highlight the importance and applicability of ancient Indian conservation principles in the present age when environmental pollution and climate change have started showing negative impacts on the earth including humankind. Cultural literacy is important for social reforms and environmental education. Hence, extracting such knowledge from ancient texts systematically and logically becomes relevant today. This book is mainly based on the text Vrataraja written around 1736CE. This work emphasizes meanings and the spirit behind various festivals and rituals (that otherwise seem irrelevant today). It enables us to understand how our ancestors were in synergy with nature.
