How do I know which one I have reached?
Searching "The Way to Ultimate Calm" by Webu Sayadaw for the word "ten", the closest thing I can find is the ten paramis. I haven't heard of anybody except a bodhisatta completely realizing any of the paramis. Of course nearly everybody has some amount of patience, etc.
If you need a way to look at your progress, you should find a good teacher.
