वरुणश्चैव सोमश्च शक्तित्रयमिमे नव / वर्णानामीश्वराः प्रोक्ताः क्रमो भूतलिपेरयम्
varuṇaścaiva somaśca śaktitrayamime nava / varṇānāmīśvarāḥ proktāḥ kramo bhūtaliperayam
Varuṇa and Soma, together with these three Śaktis, make nine; they are declared the Lords of the letters—this is the order of the Bhūta-lipi.
