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 ChopraWhen you drink in nature through your senses, you deepen your awareness of the great silent intelligence flowing through all things. You nourish your mind, body, and spirit as you connect to the divine love of Being.
