By following the eightfold path, and avoiding evil extremes, the Buddha taught that an individual could achieve nirvana. He taught that nirvana, which in their language meant to blow out a candle, was a state of non-existence.
It was not a place, like heaven, but rather an actual state of non-existence. When someone reached nirvana, their soul was in harmony with the universe and they would cease to exist.
Visitors should behave in such a way that the host and hostess feel at home.
