वीरौ two brave men, वरान् great, देशान् places, शैलात् from one hill, शैलम् to another hill, वनात् from one forest, वनम् to another, चङ्क्रमन्तौ while going, ततः then, पम्पां नाम named Pampa, पुष्करिणीम् tank, गमिष्यथः you will both reach.

O brave men, pass from hill to hill, forest to forest in great countries until you reach a lake named Pampa.
