It all depends on one’s own energy system. In our Maoshan Thunderstorm sect, we do way more crazier things, so tags are pretty harmless in comparison. If you are new to energy work, fewer the tags the better. I have a little ritual every time I add a tag - and it takes about 3-days to fully acquaint myself with a new tag so that my guides do not block the energy - and then it is pretty smoothly integrated. Other than the weight loss tag, pretty much all other tags were easily integrated by this ritual I follow.
Nothing specifically for the tags, it is more for the Metauralite crystal which in turn seems to amp up the ambient energy around it. I don’t think either is necessary - because I already have them, I’ve tried to use them, but there is really no big need for these crystals w.r.t tags.
