Shu Ha Ri is borrowed from martial arts. It defines 3 levels of learning-
Shu - Imitation. You do something by copying someone else. You don't question it. The teacher gives you a prescriptive solution to a problem that covers most of your needs. It may not be the most efficient or best solution, but it is simple to learn and covers most of the situations you encounter.
Ha - Understanding. You start to see the reason behind what the teacher taught you. You modify it to still fit the core philosophy, but streamline it for you. You also start to see that the solution doesn't solve every problem and therefore seek your teacher for new ideas and solutions, or you might even seek other teachers for solutions.
Ri - Mastery. You take everything you learn and apply it at will. You solve problems by blending solutions without even thinking. When someone asks what you just did is called, there is no name because you adapted a new solution on the fly. It just worked in that situation. Your own experiences outweigh your formal teachings.
(Literally translated: Shu-> Following | Ha-> Breaking Away | Ri-> Fluency -Cockburn 2007)
- a Shu level person can not teach. They are not prepared to guide a peer in the journey of making mistakes and adapting.
- a Ha level person benefits from multiple sources of teaching.
- a Ri level person thinks in a language that the Shu level person can't understand since it is not prescriptive.
Finally, don't teach above your level. Masters learn from their students, but students posing as masters can be dangerous.
The problem with having a Ri understanding of any topic is that you don't realize it. You don't know why they aren't getting it because it is so obvious to you. Stop and remember how you got to this point and strive to help them down that journey also.
