Chapter 4: The Nature of Reality : 5.20.
5. Brahman as God or Ishvara-20.
These difficulties in proving the existence of Ishvara, as a reality somehow different from Brahman, appear, because the individual tries to shift its own values to the universal truth of things. As long as the individual exists, an Ishvara has to be postulated as its necessary counterpart. There can be no meaning in holding that individuals exist or the world exists, but Ishvara does not exist. If there is an effect, there must be a cause, also.
The cause can be denied only when the effect is denied. Ishvara is the necessary objective presentation of the implications of the experiences of the individuals. In the admission of the world and the individuals the existence of a Supreme Creator is implied.
If there is no God, there can be no world, too. The limited intelligence of the individual cannot comprehend the meaning of the universe except on the basis of an Ishvara governing it. Ishvara and the jiva are the two sides of the same coin. The two have a reciprocal relationship.
