अहम् I, अत्यङ्कुशम् unmanageable by the goad, उद्दामम् unrestrained, मदबलोद्धतम् uncontrollable through the strongth of nut, प्रधावितम् running away, गजम् इव like an elephant, दैवम् destiny, पौरुषेण with valour, निवर्तये I will turn back.

I will make destiny, the elephant, running wild on the strength of the rut, unmanageable (even) by the goad, turn back with my valour.
