Being masterless is not an arrogant condition.
It is all about 'right relationship'.
Learn from whoever can teach you something.
A great number of people can offer you knowledge and teach you new skills - seek them out if you want to.
What is important is to keep your relationship with teachers and masters in perspective.
Do not imbue the person with any additional status.
They are just a man or a woman.
The same as you.
You do not need to bow and scrape.
You do not need to pay an extortionate amount of money in order to train with them.
Treat teachers as resources and friends.
