Control and responsibility: listener question

I'm reading Real. And just to be clear I’ve read a ton of non duality so not a beginner so to speak. Could you just quickly clarify your difference between custodial responsibilities but yet having no control over say thought. It makes it feel a bit that if I have responsibility I have some control over that. Maybe just a brief clarification of what is meant by this phrase. Thank you. I like the book, just can’t quite square that. Thanks very much,
