different approaches..

There is a lot to say about "poetry writing", "colour sound therapy" and

"writing based on shapes and imagery".
Poetry writing includes bibliotherapy, narrative psychology, mataphor, storytelling and journal writing and is explained in the book "Poetry Therapy: Theory and Practise" by Nichloas Mazza. He also explains the different modes practised (receptive/ prescriptive- expressive/creative-symbolic/ceremonial mode ).
I have also come across the "National association for poetry therapy", which is a foundation created 1993 following the purpose of supporting the field of poetry therapy and receiving tax-deductible donations, endowments and grants from individuals and organizations to further the goals of the NAPT and the field of poetry therapy. The community consists of "healers and lovers of words and language." As poetry therapists, they say that they "use all forms of literature and the language arts, and they are united by their love of words, and their passion for enhancing the lives of others and themselves."
Second, "colour and sound therapy" is also a good way of curing. I spoke to a Scandinavian friend about it and she mentioned a musician called Melody Gardot, who was treated with music/sound therapy after having a "close to death" accident. And was healed. 
And "writing based on shapes and imagery" which is directed more towards art therapy.I feel it encompasses the same feeling and process of healing. And while some traditional art classes may ask you to paint or draw from your imagination, in art therapy, your inner world of images, feelings, thoughts, and ideas are always of primary importance to the experience.
