This is a squirrely topic. Everyone has an inner life, but my impression is there is some distrust in them. Witness for example that persistent notion of a "loop". But, what are these inner worlds? How are they to be assessed? the other persistent notion is "healthy", but what's that?
See, healthy, obviously, is some kind of balance between inner and outer. The inner world doesn't wander too far of the outer path. But, it's kind of weird to press too closely to the outer path too. You lose the independent aspect to your personality.
So, the inner world... it makes people nervous to talk too freely of what's in there, but if there's nothing in there, there's no "you" either... so what are they, these inner worlds?
