Meeting my alters just came. But once I noticed they were there, I learned to meet with them and work with them. We have a great working relationship now but it took a while. They each have their own safe place and there is a meeting place where we can have a "family meeting". Now I work with each, hopefully on a daily basis, and try to help them develop a peaceful and meaningful existance. As the need arises, they introduce themselves to me and we start working from there. This work may involve meditation and relaxation, but they will make themselves known when they are ready. Then just help them be safe and know that you will be there for them and thank them for being there when you so desperately needed them.
