This is the "Conventional" homoeopathic proving of Spectrum (otherwise known as Rainbow). "I (the author) had fallen into the abyss, the infamous "Long dark night of the soul"... The feeling is of being at a transition point. Many provers found themselves dealing with deeply ingrained blocks. Main issues arose relentlessly and had to be dealt with.... This is a deeply miasmatic remedy". Issues such as profound feelings of separation, alienation, states of nervous exhaustion, ME, even possibly schizophrenia, show the correspondences between this and the picture of Rainbow in the meditative proving.
