atītānāgataṃ vetti vinā liṃgairbhavāniha ..
tasmātkuru prasādaṃ me yathā syādbrāhmaṇaḥ sutaḥ ..
kṣatriyasya tu putrasya bhavānnārhaḥ kathaṃcana .. 6.166.40 ..

You know the past and the future without external signs here. / Therefore, grant me grace, so that my son may be a brahmin; / for a kṣatriya son is by no means fit for you.'
