I discovered Tsultrim Allione's book a couple of years ago and I have not hesitated recommending it to clients and friends since that time. It is a potent modern adaptation of the Tibetan vajrayana practice called Chöd, made accessible for the modern person whether they are buddhist or not. The principle behind Feeding Your Demons is that our darkest and most frightening fears, anxieties or addictions (our demons) can be befriended and transformed.
With the surprisingly simple yet radical technique one 'feeds' the demon whatever it wants until it becomes completely satisfied! This takes the form of a meditation in which the demon is first personified and given shape before feeding it and finally transforming it into an ally.
Those with new age proclivities will seize upon the totem-like 'ally' that the method produces as the end goal, but folks with some background in Buddhist meditation of vajrayana variety will know that the true power of the practice lies in the bit where the ally is dissolved into the practitioner and they rest in unstructured awareness. This unstructured awareness neither grasps nor rejects anything in that moment and therein lies its incredible deep healing capacity - because this state momentarily introduces the meditator to their own deepest nature: unconditioned freedom. This is the greatest magic of all.
Tsultrim Allione compassionately and expertly teaches the method using case histories and stories of the most moving variety and by the end of the book the reader has been given ample examples of how to apply this technique in almost any kind of situation. If you want to learn to work with even the most difficult or painful emotions, addictions or memories I cannot recommend Tsultrim Allione's teachings highly enough.
