The mind is the instigator. The body on its own doesn’t have anything to do. It simply acts under the orders of its boss: the mind. The body doesn’t know a thing. It depends on the boss’ orders. So when the boss says, “Enough! No more!” then that’s the end of the matter. The mind doesn’t struggle or thirst. What struggles and thirsts is the aggregate of fabrication (sankhara). If you latch on to fabrication, that’s the essence of suffering — big-time suffering. If you look at the body, you’ll see that there really are no issues there. The issues all come from fabrication. If the mind can break through and understand this attachment to the body, then where else will desire come from?
