nagnāḥ pātakinaścaiva hanyurdṛṣṭyā pitṛkriyām /
apumānapaviddhaśca kukkuṭo grāmaśūkaraḥ //

Men who disgrace their family or who injure their family by separating themselves from the śrāddha, naked men and criminals may destroy the ceremony to the pitṛs with their glance; a eunuch, and a man repudiated by his relations, a cock, and the village hog, and a dog, each ruins śrāddhas by his look, and so also do Rākṣasas.
