"crystal-healing"
I didn't believe in this, at all, but had an afternoon to spare when i was recovering from a major illness. Using Crystals helped me to meditate more deeply, i also found "Path journeys" were clearer and better.
These are used for lots of issues, i have clients that have used them to come through abuse, experienced as children.
These therapies can and do help, in situations that taking medication won't do it, the act of controlling our breathing etc helps give clarity of thought.
If you have never needed that, then fine, like counselling etc, but some do find that they recover using these techniques.
Depression is on the increase, don't knock anything that can help, is my attitude.
