One way to cut the cord is another method psychic attacks defense ..
Go into a meditative state.
See your body.

See all the cords extending from your etheric body. Some of those cords you will want to keep, be they relationships with your kids, SO, spouse, family, parents, friends, etc.

Some of those you are going to want to sever; ex-boyfriends, ex-husbands, friends and family that are no longer in your life, co-workers from jobs that you don't even work at anymore.

See those cords attaching into your body with a bungee-cord type of hook/attachment.
Pick one cord at a time...pull that cord towards you to give you a bit of slack to be able to unhook it from your body without tearing it out.

Cut the end of the cord that was attached to you...sometimes just a blade or axe won't do it. Sometimes that hook will be as big as an anchor.

KNOW that you will have whatever tool available to you that will cut the end off that cord so it can not reattach itself to you.

DO NOT ATTEMPT TO CUT THE OTHER PERSON'S END. You only need to worry about your end.

Without the hook on it, it can not reattach itself to you.
Now, that said...an experienced psychic vampire can reattach that cord once they realize they are not attached to you any longer. So you may need to do this several time over the course of a couple of months.

I've been known to call on Archangel Michael to cut one cord with his flaming sword. I just could not get it done on my own. Needless to say, that one never came back.
