My tattoo is specifically kanji symbols for Ninjutsu, which is the closest I have to a religion. It's a practice that encourages usefulness, survival, and courage. But, it reminds me that everything I learned while a christian wasn't bad, and I should hold on to those things that were helpful to me. It's very easy to grow resentful, which isn't useful at all.
Seems like you're the only regular poster around here. It's so quiet on these boards.
