I’m currently reading this ebook from Personality Junkie. For anyone who is interested in MBTI I highly recommend it. I’ve been following the Personality Junkie blog for quite some time and always interesting articles surrounding MBTI. This ebook has a nice 8 page section about INFJs and is one of the best descriptions on INFJs I have ever read. It even goes into the depth of describing parts of the INFJ personality that I never seen in other articles, like the disembodiment which I feel is a big part of myself as an INFJ.
