वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
छायाशापात् पदं चैकं यमस्य क्लिन्नमुत्तमम् पूयशोणितसम्पूर्णं कृमीणां निचयान्वितम्
chāyāśāpāt padaṃ caikaṃ yamasya klinnamuttamam pūyaśoṇitasampūrṇaṃ kṛmīṇāṃ nicayānvitam
Из-за проклятия Чхаи одна нога Ямы тяжко изъязвилась — мокрая и зловонная — полная гноя и крови и кишащая грудами червей.
Suta Goswami (narrating to the sages of Naimisharanya)
It frames karma as pasha (bondage): impurity and harm inevitably mature into suffering, motivating the pashu (soul) to seek Shiva (Pati) through dharma and Shiva-puja for purification and release.
Indirectly: even Yama, the enforcer of dharma, is subject to karmic consequence and curse, highlighting that only Shiva-tattva stands beyond bondage while embodied agents remain within the law of cause and effect.
No specific rite is stated; the takeaway aligns with Pashupata discipline—ethical restraint and expiation (prāyaścitta) as preparatory purification supporting Shiva-upāsanā that loosens pasha.
