TRANSLATION
In this life, an envious person commits violent acts against many living entities. Therefore after his death, when he is taken to hell by Yamarāja, those living entities who were hurt by him appear as animals called rurus to inflict very severe pain upon him. Learned scholars call this hell Raurava. Not generally seen in this world, the ruru is more envious than a snake.
PURPORT
According to Śrīdhara Svāmī, the  ruru  is also known as the  bhāra-śrīṇga  ( ati-krūrasya bhāra-śrīṇgākhya-sattvasya apadeśaḥ saṁjñā ). Śrīla Jīva Gosvāmī confirms this in his  Sandarbha :  ruru-śabdasya svayaṁ muninaiva ṭīkā-vidhānāl lokeṣv aprasiddha evāyaṁ jantu-viśeṣaḥ.  Thus although  rurus  are not seen in this world, their existence is confirmed in the  śāstras .
