It's often the small things that make a difference.
Giggling through an otherwise boring transaction in which the bank staff just can't spell your name (three times). Gliding through traffic after a satisfying workday. Finding the perfect parking spot even thought it's 8pm. You feel you have the karma and nothing can touch you.
Sure, having karma is itself a contradiction in terms. Karma just is, like grace. No one owns it.
Like The Zone. Capitalized. Mysterious. Undefinable. Without clear borders. It's a strangely satisfying state of mind that comes from nothing (no drugs, sex or rock and roll), probably doesn't last too long, but what a high when it's there!
