How is Brahman different from Ishvara?

Brahman is the universe as the knower deity, knowing the one within is deity.
Ishvara is God as the perpetuator deity, perpetuating the one without as the deity
to be a para deity. After entropy of consciousness, the one within (i.e., deity
within) becomes the one without (i.e., the deity without) and conceives the
entropy value to be God who is perpetuating the reality of the one without.
When we are not confident of the gifts Mother Nature has given to us to fulfill our
wishes, we conceive others as God, wishing they will fulfill our wishes and begin
devoting our energy to servicing the well-being of others. Thus, we become the
medium for the illusionary production of God, as we begin personifying the God
element to fulfill everyone’s wishes until our entropy.
