karṇau ca nāsike vakṣo jāyeran māsi pañcame /
kaṇṭharandhrodaraṃ ṣaṣṭhe guhyādirmāsi saptame //

With all limbs and minor parts complete, the fetus reaches eight months; / in the eighth [month] the soul moves again and again in the mother’s womb; / when the ninth month is reached, the vigor in the fetus becomes firm.
