The following applies to many disciplines:
Rules are for apprentices so that they don’t stumble that hard.
A master doesn’t need rules.
A master will sometimes break the rules, and it leads to good results.
In fact, masters (or their disciples) write the rules.
But masters are aware that their rules are just a crude approximation of their wisdom.
(Disciples are not necessarily aware of that.)
These words came to me during my morning meditation.
