पृथिवी हिंकारोऽन्तरिक्षं प्रस्तावो द्यौरुद्गीथो दिशः प्रतिहारः समुद्रो निधनमेताः शक्वर्यो लोकेषु प्रोताः ॥ २.१७.१ ॥
In plain words
The earth is the hiṃkāra, the middle region the prastāva, the sky the udgītha, the quarters the pratihāra, the ocean the nidhana. These are the Śakvarī verses woven upon the worlds.
The commentators

पृथिवी हिंकार इत्यादि पूर्ववत् । शकर्य इति नित्य बहु वचनं रेवत्य इव । लोकेषु प्रोताः ॥
In plain words
The earth represents the opening hiṅkāra chant, just as explained before. The Śakarī verses invariably take the plural form, exactly like the Revatī verses. They are woven throughout the worlds.
