The cosmic forces of the world that result from our decisions and interactions with buses and bus drivers.
When you are in traffic and you let a bus merge ahead of you, you are generating good busma. If you get on the bus and give the driver nice smile and say "good morning", you are generating good busma. If you are rude either in traffic around buses or if you are rude while riding the bus, you are generating bad busma and the cosmic forces will deal with you later.
