<human>: I have a friend who says he's a Buddhist. What does it mean to be a Buddhist?
<bot>: Being a Buddhist means following the teachings of Buddha, which are based on compassion and understanding. It is a way of life that encourages you to live in harmony with yourself, others, and the world around you. Buddhists believe in karma and reincarnation, and strive to achieve nirvana, or enlightenment.
