The above three words in Sanskrit and eleven in English express the essential Hindu outlook on the world. It is a reverential attitude towards all of life, from the smallest animal and tallest tree, to the longest river and mightiest mountain, and even the stars and planets. Writing in Living with Siva, Sivaya Subramuniyaswami urges: "Lets worship the Earth. It is a being—intelligent and always giving. Our physical bodies are sustained by her abundance. When her abundance is withdrawn, our physical bodies are no more. The ecology of this planet is an intricate intelligence. Through sacrifice, which results in tapas and sadhana, we nurture Mother Earth's goodwill, friendliness and sustenance. Instill in yourself appreciation, recognition. We should not take advantage of all this generosity, as a predator does of those he preys upon."
