I have 4, all have spiritual significance, 2 are "initiation" symbols,and mark "Rites of passage" and the Green Man on my arm is very important to me for personal reasons. Receiving all of them was an awareness raising matter(it may be the endorphins released during the process) and I felt "changed" for the better afterwards, but that may be due to the event the tatoos were commemortaing rather than the symbols.
