Arjuna and the Hunter 9.12

9.12

ekatām iva gatasya vivekaḥ kasyacin na mahato 'py upalebhe
bhāsvatā nidadhire bhuvanānām ātmanīva patitena viśeṣāḥ //

Though desiring not to be parted from their females, the birds that must be separated at night,
the pairs indeed suffered separation; the decree of time is truly inescapable.
