Krishna answers the remaining questions. Adhibhuta — the material world — is everything that changes and perishes. Adhidaiva — the divine principle — is the cosmic being. And adhiyajna — the one who presides over all sacrifice within the body — is Krishna himself.
There is something deeply reassuring in this last statement. Krishna says: within your body, the one who inspires every good act, who sustains every offering — that is Me. Like a mother quietly overseeing everything in the household, God sits within every being, gently guiding from the inside.
God is not distant or unreachable. He dwells in the heart of every living creature. This is one of the Gita's most comforting assurances.
