etau sthitau duḥkhaharau revāyā uttare taṭe .
tāvabhyarcya tathā natvā samyagyātrāphalaṃ bhavet .
adṛṣṭapūjitau tau hi narāṇāṃ vighnakārakau .. 28.142 ..

These two, destroyers of sorrow, stand on the northern bank of the Revā. / Having worshipped them and bowed down to them, the full fruit of pilgrimage is attained; / for unseen and unhonoured, they cause obstacles to men. // 28.142
