And you have no knowledge of psychology, or spirituality, yet it doesn't stop you from making judgements or sharing your views, or for that matter, trying and failing miserably at psycho-analyzing me. I never pretended to be a scientist. And I never said that spiritualism was absolutely right. You on the other hand did fail to see my point about actually being openminded and valuing both for what they are. Grand.
Look, the amethyst example was one I used to explain stuff. I know you know more about stones than I do. I never claimed to know everything, it's all over that post. And what I shared was that science discovered that they send out vibrations. I'm sure you can use google to verify that. At no point did I ever claim that amethyst actually does what spiritualism says, I said that this is how it's experienced by many.
As for the healing effects, the colour itself can put you in a mindset that has an influence on you. And the self-healing capacities of the body could potentially be activated by that (power of positive thinking, hell, the reduction of cortisol in the blood coz you are finally able to relax). As we all know, chronical stress does harm the body. Being able to relax would therefore help the body self-heal. Also, don't count on me for this 'debate'. I've had it too many times, and it's not worth it, imo. So I'll let you NTs fight it out.
