भूवायुकनकार्णोद्योःशब्दाद्याश्च तथा दश । आशान्वयेदशपुनः प्रवृत्ता इति कथ्यते १६ ।

वेदादौ च प्रयोज्यं स्याद्वंदने संध्ययोरपि । नवकौटिजपाञ्जप्त्वा संशुद्धः पुरुषो भवेत् १८ ।

A further repetition for nine crores of times enables him to win over the Earth element. A further repetition for nine crores of times enables him to win over the water element.
