krsna-saktye prakrti haya gauna karana
agni-saktye lauha yaiche karaye jarana
krsna-saktye—by the energy of Krsna; prakrti—the material nature; haya—becomes; gauna—indirect; karana—cause; agni-saktye—by the energy of fire; lauha—iron; yaiche—just as; karaye—becomes; jarana—powerful or red-hot.
Thus prakrti, by the energy of Lord Krsna, becomes the secondary cause, just as iron becomes red-hot by the energy of fire.
