Ken Wilber, Shadow Work

"...The shadow can be feelings of anger, jealousy, power drives.... that at some point in the past these feelings became uncomfortable and we pushed them out of awareness, we project them onto other people, "I am not angry, but that person over there is angry", or displace them or disguise them in morbid forms.......once you fill your world with your own projections you are out of the now awareness, these unconscious aspects are one of the primary things that pull us out of now awareness..once we identify with our shadows they soften and are much less likely to be projected.... Even long term meditators can have shadow elements..........
