आत्मघाती स विज्ञेयः सदा त्रैलोक्यघातकः । शिवनिंदां विधत्ते यः स नाभाष्योऽधमाधमः
ātmaghātī sa vijñeyaḥ sadā trailokyaghātakaḥ | śivaniṃdāṃ vidhatte yaḥ sa nābhāṣyo'dhamādhamaḥ
Know that the one who engages in reviling Śiva is a slayer of his own self—ever a destroyer of the three worlds; he is the lowest of the low and unfit even to be spoken with.
Skanda (deduced: Kāśī Khaṇḍa commonly Skanda → Agastya)
Reviling Śiva is portrayed as spiritual self-harm and a cosmic-level wrong, demanding strict avoidance.
Kāśī’s Śaiva sacred environment is implied, where reverence toward Śiva is foundational.
No positive rite; the instruction is a strong prohibition and social-religious avoidance of Śiva-nindā.
