3.3.2

kṛṣṇe kośakṣayaṃ vidyād rakte vāhanasaṃkṣayaḥ | piṅgalaḥ pārthivaṃ hanyād rāṣṭraṃ hanyāt tu kekaraḥ ||

With a dark-eyed one, he should know loss of treasury; with a red-eyed one, destruction of mounts; / a yellowish-eyed one would kill the ruler, while a squint-eyed one would destroy the kingdom.
