Srimad Bhagavatam Canto 11, Chapter 11, Text 16

SB 11.11.16

na stuvita na nindeta
 kurvatah sadhv asadhu va
vadato guna-dosabhyam
 varjitah sama-drn munih
 
Translation: 
 
A saintly sage sees with equal vision and therefore is not affected by that which is materially good or bad. Indeed, although he observes others performing good and bad work and speaking properly and improperly, the sage does not praise or criticize anyone.
