So, what makes you a Buddhist?
You may not have been born in a Buddhist country or to a Buddhist family, you may not wear robes or shave your head, you may eat meat and idolize Eminem and Paris Hilton. That doesn’t mean you cannot be a Buddhist.
In order to be a Buddhist, you must accept that all compounded phenomena are impermanent, all emotions are pain, all things have no inherent existence, and enlightenment is beyond concepts.
~ Dzongsar Jamyang Khyentse Rinpoche
