Creating Waves of Awareness
This is an interesting topic. I will start from myself. When I take some remedy, my diet changes mostly to positive. If the remedy is right, my whole system changes as well as my needs. I don´t have so much need for coffee or anything else "unhealthy" what I normally take.
Some years ago when I had my first homeopathic session and a homeopath told to me what to avoid I didn't listen to her and I think many people don't listen really. They don't like to be told what to do, so also what to eat and what not. I think the change has to come from within and comes in the process of healing. To people who are not ready to change, their eating habits will remain (or will come back) and it is not of big use to tell what to avoid. Of course it is advisable to propose some alternatives but in a way they don't feel like something is forbidden. People are like children, if you tell them to do something they will do the opposite.
How to awake an interest for alternative diet solutions in the cases where it is really not good to take certain food? A homeopath should think how to propose something in a proper way so that a patient doesn´t get it dogmatic. It is an art to awake the interest in the patient or change in his mind, the same art as the healing. All goes together.
So I´ll end with joke: perhaps if you tell them eat sugar, drink coffe and alcohol as much as you can, then they will start to think what is this homeopath telling, he must be crazy.... and will not take all that.... homeo principle ;)
