Addiction is craving fulfillment from something that cannot provide fulfillment. In this sense it is not different than the basic mechanism of ignorance that keeps everyone in bondage. With substance addiction the mind/body sets up a vicious cycle that perpetuates the dependence.
Deepak ChopraYour body, which is bonding millions of molecules every second, depends on transformation. Breathing and digestion harness transformation. Food and air arenโt just shuffled about but, rather, undergo the exact chemical bonding needed to keep you alive. The sugar extracted from an orange travels to the brain and fuels a thought. The emergent property in this case is the newness of the thought; no molecules in the history of the universe ever combined to produce that exact thought.
