since early times people had 'magical' objects to help them. Many times it was particular stones that had different properties.

I think its nice for one to have certain key objects during a psychedelic trip, but its more about the relationship one has to that object than what exactly it is.

I am worried about this crystal story because too much new age garbage piled on top of any possible real knowledge. Nowadays there's too much of these 'crystals to energize the room' kind of thing. 

I have had trips where I saw how each object creates a certain psychological impact on us. The architecture of a room, forms and colours, all influence us. Some things are quite intuitive and when I trip I try to arrange the place where I am in a 'harmonious' way (whatever this means.. I just mean the comfort feeling it gives).

There could be interesting tests done with this, but so far none really that I heard of.  Maybe some of these 'energizing healing crystals' will actually have some sort of negative influence. Possibly when tripping one could realize this negative 'something'.

Thats why I dont exactly feel the need to go after the crystals in the moment, untill I know some more reliable knowledge or come across something that I see and feel intuitively good with.
