I do not feel the sorrow of separation from a drunken state, because my temperament is already very intoxicated.

This couplet speaks to the profound depth of emotional instability. The speaker says that the sorrow of separation (जुदाई का अंदोह) from the beloved's presence (ताब-ओ-तवाँ) does not trouble him, because his own temperament (मिज़ाज-दाँ) is inherently restless and unstable (ना-तवानी). It suggests that his internal turmoil is so vast that the pain of external loss pales in comparison. It's a declaration of overwhelming inner chaos.
