Sanskrit Sukti on the importance of intelligent company

वरं पर्वतदुर्गेषु 
भ्रान्त: वनचरै सह: 
न मूर्खजनसंपर्क: 
सुरेन्द्रभवनेष्वपि// 
Varam ParvatDurgeshu
Bhraant: Vancharai Saha:
Na MoorkhjanaSamparka:
SurendrabhavaneShvapi

One might go to the forest, or to an inaccessible mountain,
Or roam with the forest animals
But one should not remain in contact with fools
Even if one gets to enjoy the palace of Indra in such company.
