It has been stated that everything different from Brahman is the effect
of Brahman. The doubt now arises whether the more remote effects of
Brahman originate, each of them, only from that substance which is their
immediately antecedent cause or from Brahman in the form of that
substance.--The decision is that they originate from those substances
only; for the text 'from air fire' directly states the origination of
fire from air.
