So , if you have control over the thought forms and change them as you want, you are not bound by the outside world. There’s nothing wrong with the world. You can make it a heaven or hell according to your approach. That is why the entire Yoga is based on citta vrtti nirldhah (the restraint of the mind’s distractions). If you control your mind, you have controlled everything. Then there is nothing in this world to bind you.
