Realized souls  avoid contact with negativity not out of fear, but out of desire to keep away from impurity though they are strong enough to destroy the impurity. 

We need not react to every opinion, every comment, or every situation.

We must choose our battles wisely because not everything deserves our time and attention. Reacting or behaving in a same way will take away our peace of mind.
