Nandin said: The universe appeal's to be existent by his very activity. The eight[4] forms of the lord represent the empirical universe. Without the five elements—ether, earth, wind, fire and water and without the priest, the sun and the moon, the world has no existence. On consideration, it is evident that the gross world consisting of the mobile and immobile beings is the gross body of Rudra. These eight are the cosmic forms of the lord.
