You are already invincible, invisible, indescribable, with no life, no personality, no thoughts, and no anxiety.
You see a body, thoughts arise and you call it “me” and “my thoughts” (because people told you it was you) but where is the “me” who is thinking this? What even is a “me”?
(Notice how thoughts cease when you search for the “me” 🫢)
You could say you are the brain but what is keeping the brain alive? There has to be something prior to neuronal activity. Be THAT and throw away the sense of “I” which is the root of all suffering.
I used to think “I” was the highest state, but problems can exist where there is an “I”. If there is no “I” there is no “I have __” or “I am __” that is the start of all trouble 🙄.
