myangelleo.....I once read.....to imagine yourself in a room with a door that has a handle on the INSIDE, that opens and closes the door...but no handle on the outside.
The "door" is your boundary. No one can get in from the outside unless you permit it....
You control the door (from the inside).....and it is entirely up to you what you will allow in and what you will keep out. The door is to protect you from what you will not allow....ever....by anyone or anything.....
That helped my understanding......
