117.2

yadi paśur upākṛtaḥ palāyeta, anyaṃ tadvarṇaṃ tadvayasam ālabheta iti. yady ākṛtivacanaḥ śabdo bhavet, anyasyālambho nopapadyate. anyasvāpi paśudravyasya saivākṛtiḥ. tasmād vyaktivacana iti.

'If the sacrificial animal that has been brought up should flee, one should seize another of the same colour and the same age.' If the word designated the universal form, the seizing of another would not be intelligible, for the other animal substance too has that very same universal form. Therefore, it designates the individual.
