The Sun is the source of all life on Earth. Many cultures around the world, especially Indian culture, recognize the Sun as the ultimate life-giver. Clearly there is no sustainability without the Sun. Spirituality may mean seeing God in everything around us and to deal with everything accordingly. True passion for sustainability flows from a deep sense of spirituality. We need to work on three levers to make our life sustainable: social awareness and action, technology creation and implementation, and public policy. All of them will lead to economically viable solutions. Only economically viable solutions can be truly sustainable in the long run.
