Religion (dharma) plays a vital role in the Hindu (Sanatana) quest for understanding and practicing harmony between nature and humanity that result into the formation of a cosmological awakening, i.e. 'transcending the universe.' The importance and applicability of such new consciousness is a sign in promoting global humanism in the 21st century, where environmental ethics and sustainability are the wheels of making the future more humane and peaceful. Arne Naess, who coined the term 'deep ecology' conceiving humankind as an integral (...) part of its environment, gives credit to Gandhi. Gandhi’s contributions help to re-awaken the human spirit to self-realisation, finally leading to revelation promoting human coexistence with nature sustainably, mostly through re-interpretation of Vedantic thought. Under the SDGs (Sustainable Development Goals) the ideas of Gandhi are recognised as a path that makes human coexistence stronger, feasible and co-sharedness, sustainable in peace and harmony with nature. This essay presents ecospiritual contextuality and its vitality concerning a sustainable perspective in line with Gandhi's vision and way of life. (shrink)
