In my opinion, the shayer is saying that by giving a little mae, his thrist increases bc instead of satisfying him, the urge to have more is greater. Ofcourse, mae means something that intoxicate u and take u to a make believe world and probaby he is referring to mehboob' s meeting which is surely intoxicating for him. He is also saying that please don't send me to maikashey, becuase i will definitely over indulge myself considering the degree of tashnagii that i have. It would be really a punishment bc i wouldn't be able to handle my slef.
