The only thing you have is your mind. The only thing you are is your mind. Everything outside of your mind is a shadow at best or often a hallucination outright.
Lots of mystic allegedly enlightened takes on what that means. To me it means I must take great care what I put into my mind. Commercials, podcasts, slop tv and movies, on and on. All content is designed with the intention of shaping your mind to the creators image of who you should be.
Be selective who you let mold your mind. Take time away from content to think for yourself and shape your own mind.
If you spend 100% of your time consuming content and never building yourself independently in silence, is there even really a thing that is you?
