A swastika is a symbol in both the Buddhism and the Bon. The swastika of the Buddhism turns clockwise. It's a symbol for infinity and sometimes the swastikas can mean sun and moon: a symbol for the university. In the Bon, the swastika turns to the left. That's because the Bon thinks clockwise brings misfortune. When you are in Tibet you have to pass the Holy buildings at the left (it doesn't matter if the building is from the Buddhists or from the Bon), or you'll be very unlucky and misfortune will lead your life.
