The most alarming situation today is the degradation of environment. There is a perpetual deterioration of environment internally, externally and cosmically. Environmental pollution is rooted in ‘Avidya’. External disturbances are sparked by the distortion of internal states, which lead to pollution, deforestation, animal cruelty, global warming, and other environmental concerns. The present book attempts to deduce ‘Environmental Ethics’ from the subtle metaphysics of Sankara Advaita Vedanta. It delves deeply into His philosophy, spiritual Sadhana, works and practical endevors in order to emphasize an environmental and eco-esthetical perspective that elevates ‘Environment’ to the status of the ‘All-pervasive Truth, Highest Good, Supreme Beauty, and Ultimate Reality.’ One can particularly see the above said viewpoint highlighted in Adi Sankaracarya’s Prakaranagranthas. The book identifies lessons of universal compassion in view of environmental harmony. It focuses on the elucidations in accordance with the teachings of Advaita Vedanta and endeavors to apply the same in the most practical manner. It is to be pointed out that no known research or book related to Adi Sankaracarya’s philosophy and environment has been carried out or published in India or abroad. Therefore, this book emerges as a unique, innovative and critical work of all times. The aim of this book is not merely to see environment in view of Adi Sankaracarya’s philosophy rather it also endeavors to kick-start a new era where ancient thoughts, philosophies, teachings and visions will be reinterpreted while being rooted in their metaphysics in order to deal with the current environmental, social, political, religious, scientific and cosmic chaos.
