Willpower does work, in fact willpower is the only think that works but for it to work we must first learn who we are. Rather that wasting time on this dependency inducing psychobabble I seriously recommend people who feel they are defined by their perceived problems to get hold of a (free) copy of the Bhagavad Gita, preferably a translation by an Indian translator, and avoid modern translations, they tend to be by western charlatans out for personal gain.
The Gita does not have all the answers, but what we learn from it is there is no single source of all the answers available to us.
Here’s a snippet from the book on addiction:
We must control the senses to be avoid addiction. Senses play an important role in the development of attachments.
The individual who is ruled by the senses becomes attached to objects. From attachment comes desire, from desire jealousy arises. From jealousy comes delusion and from delusion arises the perversion of memory.
From distortion of memory comes loss of intelligence and when intelligence is lost we become addicted. Once addicted we have lost ourselves.
Everyone ought to be aware of the risks of addiction to heroin, cocaine, alcohol or even prescription pain killers, but there are more insidious forms of addiction; to self pity, and to the seductive offerings of people offering quick fixes. Connection is important, with people, animals, literature, art and the sciences, and with our environment, but it must be our own connection. Putting a veneer of somebody else’s personality over our self — doubt and insecurities can only mask them from ourselves.
