There is a shortcut that I wouldn’t recommend but I will share it because it can help with potential context in your endeavors. I had a horrible situation once, where something was stuck in my head. Always talking and it felt like something else. Something very low vibrational and I couldn’t get rid of it no matter what I did. Felt like an implant or something. Well, Dream gave me the advice to remember that in essence, all is one. This separate thing is still a part of you, especially since it is within.
But you are supreme, remember that and take account of your own power. Reintegrate that part of you with acceptance and love and allow it to be sucked into the wholeness you are. It will be a lower part of you for a few but raise your vibration and it will be like nothing happened. I did this and the thing was gone within a day. That was all it took. But I don’t recommend this only because I think you need to have direct confirmation that -all is one- through actual experience.
I have experienced oneness over a dozen times so the belief is imprinted in me. I knew I would be safe in doing this scary kind of transmutation. Most people would get scared and feel like they are letting something else take over them and then that fear can backfire. So don’t do this. But I share this because there might be instances where the knowledge may be of use. Always remember that, you are the creator itself. You are the infinite. And you alone have authority over your body. So proclaim your rightful power.
