। ॥ ९० ॥
In plain words
Iron has no fire in it. Hold it in the flame and it glows, it scorches — the burning shows up in the iron. In exactly the same way, from contact with consciousness, doership and all the rest show up in the 'I'.
Close to the Sanskrit
Just as burner-hood and the rest, of iron, appear through contact with fire, so too, from contact with consciousness, doership and the rest appear in the 'I'.
