I know some people have strong reaction to things like crystals. I think there is a lot of silliness around them but it wouldn't bother me - I already deeply believe therapists are batshit crazy and inconsistent at the best of times - at least with a crystal one might guess at some of the craziness if one were interested in the therapist. I don't consider it the same thing as a crucifix or buddha. I consider crosses to be only religious and of a religion I do not think much of. The buddha I would see more as hey whatever - a lot of non-buddhists I know have buddhas for some unknown reason. I even have a piece of religious art in the form of a kneeling angel candle holder - a friend of my mother's sent it to me after my mom died because it was something my grandmother gave mom's friend when friend's mother died. So I am a tad sentimental about it. I see grandmother and mom -not a religious symbol of the questionable institution they tried to induct me into.
But I would not like people who don't know me giving me things for my office. That would kind of put me off. I wouldn't be thrilled even if a friend gave me something unless they knew I wanted it. I consider gifts from strangers to be a bit burdensome
