लालापिबेच दुष्प्रेक्ष्य तीर्थासुष्ठीविनं नय । आमपाके च गर्भघ्नं शूलपाकेऽन्यतापिनम्
lālāpibeca duṣprekṣya tīrthāsuṣṭhīvinaṃ naya | āmapāke ca garbhaghnaṃ śūlapāke'nyatāpinam
Lead the impure one who spits in the sacred tīrthas to the hell called Lālāpiba, hard to behold. Consign the slayer of the unborn to Āmapāka, and the tormentor of others to Śūlapāka.
Skanda (deduced for Kāśīkhaṇḍa, Skanda → Agastya dialogue context)
Tirtha: Kāśī-tīrthas (Gaṅgā-ghāṭas, contextual)
Type: ghat
Scene: Three infernal vignettes: (1) Lālāpiba—an unclean sinner forced to drink foul saliva/filth near a desecrated ghat motif; (2) Āmapāka—feticide in a cauldron of half-cooked putrid matter; (3) Śūlapāka—tormentor impaled on spears/tridents, surrounded by attendants.
Sacred places demand śauca (purity) and reverence, and harming life or causing others pain brings severe karmic fruition.
Tīrthas in general—within the Kāśī sacred geography—are upheld as holy and not to be defiled.
An implied prescription of tīrtha-śauca: maintain cleanliness and respect at pilgrimage waters; no detailed rite is specified.
