अधोलोकवर्णनम् (Adholoka-varṇana) — Description of the Lower Worlds and Cosmographic Measures
सूर्याग्निग्रसमानानां संध्याकाले हि रक्षसाम् / प्रजापतिनियोगेन शापस्त्वेषां दुरात्मनाम्
sūryāgnigrasamānānāṃ saṃdhyākāle hi rakṣasām / prajāpatiniyogena śāpastveṣāṃ durātmanām
At the time of Sandhyā, the rākṣasas who seem to swallow the Sun and the sacred Fire are under a curse; by Prajāpati’s ordinance, that malediction rests upon those evil-souled beings.
