प्राणमभ्युज्जिहते सैषा देवता प्रस्तावम-न्वायत्ता तां चेदविद्वान्प्रास्तोष्यो मूर्धाते व्यपतिष्यत्तथोक्तस्य मयेति ॥ ५ ॥
In plain words
All beings rise up toward prāṇa; this very deity is anchored to the prastāva chant. Had you chanted the prastāva without knowing her, your head would have shattered, just as I told you.
Close to the Sanskrit
They rise up toward prāṇa; this same deity is anchored to the prastāva. If you without knowing her had chanted the prastāva, your head would have split off, thus as spoken by me.
