It seems "enlightenment" really means to become aware of something one did not know before. How silly.
After some negative energy started building up, caused both by my own karma and some squatting viral aliens in my dimension (I mean they stay there because this is how things work, the law of opposites states that someone trying to do something positive will face a equal negative resistance, they do this job as part of the cosmic function) I used a number of methods to cause a relaxation which would finally externalize and cause the negativity to be under my service...
This time was extreme, but it worked. A hot bath, a bottle of white wine... only made it more intense, add some magnesium and caffeine during the day, then paracetamol and the negative energy formed into a thick but perfectly pointed spike.
I bet these aliens feel pretty stupid now, as they served me perfectly. All details left aside, concentrating negative energy into a check-mate position will cause it to start burning when the intensity is high enough, and that did the job.
I had not expected my higher self of this life to assume the form of a nine tailed fox, however.
Although, I should have guessed something was up when the internal image of the city went from blurry to fully lifelike when reading Growing Up by Ichiyō Higuchi, then an orange-red orb formed with a bang, and I saw foxes chasing their own tails through the day (the image of fox-gong).
