It is often the case that the earth human only looks at the effects of a matter, person, situation etc. and never gives much thought to the cause. It is strongly this reason why the earth human, in much of their arrogance, cannot determine the correct age of the universe, and at large, many other secrets and mysteries of Creation that continue to evade the earth human because of their ignorance and lack of open-mindedness beyond their boxed thinking. This is no exception to the case concerning health afflictions of various sorts, including but not limited to, mortal diseases and illnesses, cancers, plagues, epidemics, mental disorders, psychosis, psyche destruction, and so on and so forth.
The fact is, whether one wishes to study all the effects and how the particular disease or illness is operating, the earthling rarely ever asks themselves - how did it come about? The fact is that everything, regardless of the human's perception, works in cause and effect, and thus there is no death, illness, disease, cancer, affliction, plague, mental disorder etc. that randomly happens. Such thinking is illogical because even down to the tiniest of scales, everything operates in an action-reaction-causality-basis and thus nothing is excluded from this rule, even if the human wishes to be blinded by their emotions, biases and beliefs. Truly, even the illnesses that the human being may encounter in life does not happen by random bad luck; rather, a configuration of cause and effect that had long been at play before the human succumbed to their afflictions.
Many human beings on earth go about stressing and taxing themselves into the ground, for various purposes, beliefs, depressions and so forth, though nevertheless, they continue to drive themselves into the ground then wonder how on earth did this happen? As is often the case with loved ones who passed away, some are shocked by their sudden mortal illness or quick death; yet neither the quick death nor the illness that may have dragged the human to the grave, are necessarily to blame; rather, the proceeding causes that led the human to begin the self-destruction mechanism which is present in every human being as a failsafe measure.
The human may hold on so much to a loved one after they pass that they can grieve themselves into an early grave if they are unable to find any sort of resolution to move forward. Indeed, if one plagues themselves so much with worrisome, troublesome, depressive, self-defeating, world-ending thoughts and following feelings, then this continues to build into the psyche and turns the entire life into a nightmare. The consciousness, sooner or later, activates its own self-destruction, and from there, the inevitable death process is already at hand; for the human has already given up their will to live even if they are unaware of the mortal dangers they have brought upon themselves.
From there, any disease ranging from cancer to pancreatic necrosis is possible, including but not limited to; random slip and slides, and deaths that may suddenly occur without any warning. Yet the human subconsciously had already programmed their inevitable fate through the constant drip feeding of their dark, hellish, gloomy, burdensome, depressive, defeatist thoughts, feelings and emotions, and thus the effects are simply at hand for the causes that were already pushed into the fray. Of course it is possible even the healthy human may catch a disease or affliction, yet for such humans with a healthy, strong, persistent, overcoming consciousness, the whole matter of defeating the afflictions becomes much easier and possible versus a negating-negative-pessimistic human who had already given up all hope before the illness even afflicted them.
The fact is no human is exempt from this rule - what the human continues to nurture and sow is what they will reap for better or for worse. Thus those human beings who have been so stricken with sadness, loss, hurt, suffering, setbacks, mistakes and the like, who allow these problems, difficulties and sufferings to get the better of their forward-progression-moving-thinking, will succumb to the darkness and will indeed suffer their own pre-determined deaths. Many times the human, in their gloominess, prays to 'god' to take them as an act of tiredness of the stresses and pains they deal with in life. While 'god' cannot hear them, their consciousness certainly can, and due to free will, if the human truly chooses to die then the consciousness will provide that wish. In a sense such human beings can truly be considered suicidal because they have lost hope and lost the sense of life and life purpose.
The human of earth must always remember, even during their darkest of times, that the infinite power within them is constantly supplying the human with the necessary energy that operates in the physical existence as both positive and negative experiences so that an equalization can occur which leads to truly balanced-forward-moving-progression, and thus, no experience, no matter how incredible and amazing or difficult and painful, is ever meant to destroy the human being; rather, empower them in moving forward and accomplishing their goals, dreams and wishes which should be Creational-aligned.
The spiritual consciousness can only absorb neutral-positive harmonization waves which must come from a harmonization between positive and negative, and thus all life experiences of all sorts, regardless of good or bad, are working together to create a true harmony. If the human being configures their thoughts to such ideals then truly the whole life, regardless of rain or shine, becomes an endless beauty and a timeless pearl that is worth cherishing and worth fighting for, even in the hardest of times.
