Shugyosha

You heard right, but I don't know anything about it. I'll pass on a link though then you can check it out yourself. http://www.theninjacamp.com/summary/summary.html

For those who may have trouble calming themselves enough to be able to reach a meditative state in your home or maybe elsewhere, I recommend searching and trying at your local parks or more isolated forests surrounded by trees (especially pine trees) or near water. Nature helped me focus my energy more precisely and if it could help anyone else focus better I would have been glad to help. Meditation can be a forgotten gift for many.
