【Real * Right * Practice】
- All human questions can be divided into two categories:
1.1) What is the world like: what makes it real.
1.2) What should people do: what makes it right.
All human activities can be summarized into one: Practice.
Under these two questions, humans undertake the one activity.

6.1) For Realness: how is it possible.
6.2) For Rightness: how is it permissible.
