As long as you are looking for a feeling of detachment then you are on the wrong road. Detachment can easily be done with the actions of detachment. It can be done even if you don't feel like it...
The sooner people stop associating detachment with feelings the sooner they will understand what it means. Matter of fact, you don't even have to understand what it means.
Same as you don't have to feel love to be loving. You don't have to feel like going to work, to go to work. You don't have to feel disciplined to be disciplined.
The people who go by their feelings or wait for the feeling of detachment are slaves to their feelings. That is why it takes some longer than others. It does NOT just come when it comes. It CAN be initiated and it can be accelerated.
Just because you feel detached doesn't mean you are detached. Same as just because you don't feel you aren't detached doesn't have to mean you aren't. Stop going by your feelings. Feelings can deceive you. They can change from moment to moment.
