Diabetics and cancerics might be the sad story of the lack of evolution of man.
A diabetic probably cannot process the higher energies of good intention while the cancerics can't ground their energies at all until it goes wild.
We've probably been stuck here for absolutely all of history as homo sapiens.
I've seen the bad intentions of diabetics and it's not in their control. They're victims of bad guts.
The bad energy from the gut rises up the spine putting them in a waking nightmare of a Peonia state. Their hurtful, controlling actions stem from perceived slights, horrors and harms that they imagine are coming their way. "Terrifying dreams. Delirium. Excitement. Apprehension with anxiety, afraid to talk with any one; much affected by bad news, Ill humour. Depression with irritability."
The next state is the Baryta carb "Confusion. Bashful. Repugnance to strangers or to society, Mistrust; Scrupulous, irresolute, suspicious temper, with mistrust of one's self. Fear and cowardice.Sudden fits of passion from trifling causes, Incessant activity, cannot remember and learn."
They lose their ability to be creative, living in this survival mode.
The next state is the Apis one. The energy accumulates at the back of the head, where many autonomous, instinctive and primitive activities are located. So "cannot think clearly. Jealous, fidgety, hard to please. Whining. Tearfulness. Jealousy, fright, rage, vexation, grief. Cannot concentrate mind when attempting to read or study."
Simultaneously, or very close together, they get the extreme sensitivity of the nerves and brain of Hydrophobinum which has "thoughts that something terrible going to happen come into his mind against his will; feels impelled to do reckless things, the mental faculties are in a superior state of excitement. Imagine that they are abused, and energetically defend themselves against attacks and insults. Strange notions and Insane ideas enter his head; for instance, to throw a glass of water, which he is carrying. Inclination to be rude and abusive, Exhilarated. Ill-humour. Hypersensitiveness of all the senses. Psychic skills like clairaudience, clairvoyance."
