From Nikola Tesla: “Although the brain does not feel pain itself, it is necessarily aware of messages of physical and mental pain; so also in some ways the mind does not feel pain in the same way as the body or emotions: mental pain is evidenced in confusion, obsession, exhaustion and depression generally. When the mind is in pain it can become over-reactive or under-reactive, either skittering from thought to thought without focus or stumbling and moving slowly, as though you are trying to think through sludge or glue.
“Emotional pain can be the trigger for some of this, especially grief and loss; however, physical situations are also the source: brain damage or dysfunction on the cellular level, as well as lack of sleep or improper nutrition in the physical sense as well as lack of mental “nutrition:” a static, repetitive, burdensome round of days upon days as when one is in prison, living alone or even caring for someone without respite, or even living in situations where there is no mental stimulation and the same, tired old opinions, perceptions and attitudes are replayed continually.
“This lack of mental stimulation can of course be set aside when you come into new situations, especially when you are in situations of learning like college or studying for a new job; this is part of the reason why college towns can seem so light and vibrant: new things are being learned and experienced constantly. That this is a tragedy when too many college students numb, silence or warp this vibrant, challenging influx of new ideas, perceptions and challenges with alcohol and other self-altering drugs: this specific issue must be addressed in another article.
“Suffice to say: your mind is hurt by stagnation but, rather like having a limb that has ‘fallen asleep,’ exercising the mind after long disuse or over-use through trying to make sense of insane, conflicting and/or threatening perceptual confluences, getting free of the static mental traps can hurt as well.”
