There are two aspects of nature that are connected to each other - our inherent nature that defines us, and the outside nature that sustains us. Our continued existence as a species depends heavily on the outside nature and it is therefore important to live in harmony with it. Our actions not only affect us but also the survival of other species. We must cultivate our inherent nature in such a way that it leads to compassion, selflessness and kindness. We can only be sustained if we sustain the nature around us.
