sa ya eṣa bahusāraḥ sa hāpaśavyastasmāttādṛśam paśukāmo yūpaṃ na kurvītātha ya eṣa phalguprāsahaḥ sa ha paśavyastasmāttādṛśam paśukāmo yūpaṃ kurvīta

Such a (sacrificial stake) as has much substance is not auspicious to cattle, whence he who desires to have cattle should not make such a one his sacrificial stake: but such a one as is of little hardness is auspicious to cattle, whence he who desires to have cattle should make such a one his sacrificial stake.
