LAMA ZOPA RINPOCHE
You are the guru and your mind is your disciple.
One must practice with the bodhisattva attitude every day. People can’t see your mind, what people see is a manifestation of your attitude in your actions of body and speech. Pay attention to your attitude all the time, guard it as if you are the police, or like a maid cares for a child, like a bodyguard, or like you are the guru and your mind is your disciple.
