Who bears sin on the earth?

गिरिजोवाच |

Parvati said (to her friend Vijayaa)

न केवलं भवेत्पापं निन्दाकर्तुः शिवस्य हि |
यो वै शृणोति तन्निन्दां पापभाक्स भवेदिह || 49 ||
शिवनिन्दाकरो वध्यः सर्वथा शिवकिङ्करैः |
ब्राह्मणश्चेत्स वै त्याज्यो गन्तव्यं तत्स्थालाद्द्रुतम् || 50 ||

Not only the one who criticises Lord Shiva commits a sin, those who
listen to that criticism also bear the sin on the earth.

These two shlokas also appeared as shlokas 37 and 38 in Chapter 28 of
Parvati block of Rudra Samhita. Chapters 26 to 28 of Parvati block of
Rudra Samhita have several common shlokas with this chapter.
