Aspects of Shiva - Bhuteshvar
Once it was decided that animals would eat each other for surviaval and the meker ones would eat the plants,the question arose that on what would the plants live. Shiva decided they would live on the five elements-earth, air, light, water and ether. So he came to be known as Bhuteshvar, master of the elements.
