O cupbearer, in my view, someone is not a true drinker at all if they still distinguish between sobriety and intoxication.

Speaking to the cupbearer, the poet suggests that a genuine seeker or lover transcends the rigid boundary between worldly reason and ecstatic abandon. If someone is still calculating their limits and distinguishing between sobriety and intoxication, their surrender is incomplete. In the highest state of love, conscious awareness and divine madness dissolve into one seamless experience.
