The Paraliminals create new neural pathways. The old ones are still there and you will still notice them but now your feeling have a choice. What would work better for you. Getting anxious even though you have these thought or the feeling of calm.
I think it's a good thing that we still have the old thoughts even if we have new choices for feeling. If the old thought just disappeared we'd be wondering who we are what happened to that person. Also it's not always about eliminating thoughts or feelings but having more options. Now you're learning by experimenting with those new options because you're still testing the water you need thos old thought.
In some ways creating new neural pathways is like moving into a new house you bring many old habits with you but you have to drop some of them because they just don't work in that house. You still mentally, for a split second, go the same bathroom but in the new house you have to change the direction and it doesn't change you long to do it. It occurs from time to time for a couple of months, Then suddenly about 6 months down the track it feels like you've been living in that house forever and the habits from the old one are modified or dropped.
