My thoughts.
Stop going to external sources for savior/letting go. Find your own way to savior/letting go. That's the only way it will ever really stick.
Every craft in history has followed the path of passing down what the last person learned and studying with teachers. Zero exceptions. Zero except in superhero movies. Not one thing any of us does was not learned first and then integrated.
But good teachers show the technique or practice and then encourage you to make it your own, or even abandon it entirely.
I agree with your sentiment, it all comes down to you. But,
It's all internal. It's all you. That includes the people and resources you attract. Don't deny yourself what others offer to you- the idea that you need to do and learn everything by yourself slowed me down for years. don't buy what you don't want to buy and ignore what doesn't resonate with you, but if something comes across your path, then you decide to look at, then you implemented and do it your own way, that's still all you
It's never the technique that lets something go, it's always you that does it.
Good resources don't deny this and don't tell you some special question or recording that's actually doing work.
Trust your instincts about what to look at and what to ignore I'm just saying there's no real difference between internal and exernal, and to watch out for the trap of not studying or checking out send you come across that spark you, just because it's an idea that you're supposed to do it on your own
