। ॥ ३३६ ॥
In plain words
From air comes fire, from fire the waters, from the waters earth — each in its turn. And in that power, tamas is what predominates: you can see the inertness in everything it makes.
Close to the Sanskrit
From air, fire; likewise from fire, the waters; from the waters, earth — in sequence. Of that power, the predominance of tamas [follows], because of the observation of inertness in its effect.
