इन्द्राद्यास्त्रिदशाः पतन्ति नियतं भोगक्षये ये पुन-र्जायन्ते मनुजास्ततोपि पशवः कीटाः पतङ्गादयः ।ये मातर्मणिकर्णिके तव जले मज्जन्ति निष्कल्मषाःसायुज्येऽपि किरीटकौस्तुभधरा नारायणाः स्युर्नराः ॥
In plain words
Indra and the gods fall too. The merit runs out, and down they come — reborn as human beings, and lower still as cattle, as worms, as moths. But the people who go under in your water, Mother Maṇikarṇikā, come up without a stain, and they wear the crown and the Kaustubha gem: they are Nārāyaṇa, all the way into union with him.
Close to the Sanskrit
Indra and the other gods inevitably fall when their enjoyment is exhausted; they are born again as humans, and lower than that as beasts, worms, moths and the rest. But those men, O Mother Maṇikarṇikā, who plunge into your water, stainless, become Nārāyaṇas bearing crown and Kaustubha gem — even unto union itself.
