kaleryugaṃ mahāghoraṃ prāpya pāpasamanvitam ..
nānyenā'sminnupāyena dharmmaḥ svargaśca labhyate ..
vinā yātrāṃ mahādevi someśasya na saṃśayaḥ .. 9 ..

Having reached the terrible Kali age full of sin, / righteousness and heaven are attained in this [age] by no other means / except for a pilgrimage to Someśa, O great goddess; there is no doubt. 9.
