tasya ceyaṃ parā māyā kalā śirasi dhāritā ..
sā śaktirdevadevasya viśvākārā parā priye ..
mohayitvā tu saṃtānaṃ saṃsārayati pārvati ..23..

And this supreme Māyā of his, a digit, is borne upon [my] head. / She is the supreme power of the God of Gods, whose form is the universe, O beloved; / having deluded progeny, she causes it to transmigrate in saṃsāra, O Pārvatī. 23.
