 I send out heat in the form of fire, the sun etc. I hold back the rain during summer. Likewise, I pour out the rains during the rainy season. I am immortality as well as death - I am both these conditions through which the world lives and dies. Why say more? I,am "the being and the non-being". Being is that which exists in the present time. Non-being is that which existed in the past and that which may exist in the future, but is not experienced now as existing. The meaning is that I alone am existent, having all the entities for my modes, as all intelligent and inert beings existing in all states, constitute my body. In this way, they (the wise) worship me, contemplating, through the realisation of my essential entity, as the entire universe distinguished by names and forms and characterised by varied pluralities constituting my body. I alone exist; all the pluralities are only my modes.
