tatra yā kurute snānaṃ tṛtīyāyāṃ samāhitā ..
nārī mārgasite pakṣe sā saubhāgyavatī bhavet ..
atha daurbhāgyasaṃpannā kāṇā vṛddhā'tha vāmanā ..
abhīṣṭā jāyate sā ca tatprabhāvāddvijottamāḥ .. 8 ..

Whatever woman, composed in mind, bathes there / on the third day of the bright fortnight of the month of Mārgaśīrṣa, becomes fortunate in marriage. / Even if she is afflicted with misfortune, one-eyed, old, or a dwarf, / she becomes beloved through its power, O best of brahmins."
