festival

Garuda purana

The vile are ever prone to detect the faults of others, though they be as small as mustard seeds, and persistently shut their eyes against their own, though they be as large as vilva fruit.

Henry Rollins

Each year, every city in the world that can, should have a multiday festival. More people meeting each other, digging new types of music, new foods and new ideas. You want to stop having so many wars? This could be a step in the right direction.
