I was at Barsana,Mathura to witness the world famous Holi celebration.At the entrance of the temple complex there was a place specified for dancing,singing the hymns and celebrating as inside of the temple was too crowded to celebrate.I saw this young man playing Dhol(double-sided barrel drum) continuously for 2-3 hours,people dancing and singing to Lord krishna.I felt a lot of positive energy at this place.
