Hinduism is a religion that is very near to nature. It asks its followers to see God in every object in the Universe. Worship of God in air, water, fire, Sun, Moon, Stars, and Earth is specially recommended. Earth is worshipped as the spouse of God, hence very dear and near to God. All lives on Earth are considered as children of God and Earth.
Sri Krishna in the Bhagavad Gita says:
I pervade the Universe. All objects in the Universe rest on me as pearls on the thread of a garland.
The Upanishads narrate that after creating the Universe, the Creator entered into each and every object to help them maintain their interrelationship. The Upanishad says “tat sristva ta devanu pravisat”: (“after creating the universe He entered into every object created”). Therefore to contribute toward the maintenance of this interrelationship becomes worship of God. Hindus believe that there is soul in all plants and animals. One has to do penance even for killing plants and animals for food. This daily penance is called visva deva. Visva deva is nothing but an offering of prepared food to the Creator, asking His pardon.
The Hindu religion gives great importance to protecting cattle. At every Hindu house there is a cow and it is worshipped. The cow is a great friend of humans. It nourishes us through its milk and provides manure to grow our food. This it does without any extra demand—it lives on the fodder got while growing our food. Advanced countries have started to realize the harmful effects of consuming food grown with chemical manure. When we use chemical manure, the topsoil loses its fertility. This generation has no right to use up all the fertility of the soil and leave behind an unproductive land for future generations.
