Once I was celebrating a festival with some druids. I saw a mound of earth near the ground where we were going to be celebrating, made some comment about it and got in return “oh, that’s just a new mound” to which I answered that everything was new once.
Just because something is new or is neo-pagan does not mean that it doesn’t work. Everything is worthy of investigation. I’ve used a weeping willow as my circle, which is a new thing, but it works. Our ways become stale and hidebound if we never try anything new.
Just because something is old it doesn’t mean that it will work. There are recipes for flying ointments which no-one would use today because we know they are poisonous.
