Hi,
I was attuned in 2nd level 6months ago, and I did not feel anything special. It was after work and meditation that I felt "other"type of energy:the sensitive one. Still I cannot "see" my guides but I do feel them. Auras can be seen without reiki, you only need to practice your peripherical sight. With time and practice, first you will be able to see a bright contour and after colour.
