Criticism

शिवमायावर्णनं नामैकत्रिंशोऽध्यायः
Lord Shiva's Maya (illusion power) description Chapter 31



ब्रह्मोवाच |
Brahma said (to the Devas)



परनिन्दा विनाशाय स्वनिन्दा यशसे मता || 23 ||
Criticism of others leads to destruction; self-criticism is believed to lead to fame.

This repeats in Shatrudra Samhita, Chapter 35, shloka 16.
