Should I find a guru or a master?
There are many sources of inspiration which can play that role.
I would say experiment with it.
Listen to your feeling, your impression.
It has to feel good.
Nowadays, many spiritual adventurers choose to travel “solo”.
They prefer to find in themselves the source of inspiration.
Or they get together without a central source of authority. All that is great.
On the other hand, a guru can save you time. It is a source of inspiration and a guide.
Find what is the best for yourself. I believe that all options are open.
