There’s no such thing as an enlightened master, or a guru. Enlightenment is not an achievement or something that is earned, it is the exact opposite of these things. People call enlightened ones masters and gurus, and it’s a reflection of their confusion. An enlightened person may play a temporary role of a “master” to help them see through their confusion, which, if successful, always results in them not seeing him as any kind of a “master” any longer.
