I am also reading his Psychology class book with him. I am remembering something of the wonder of the brain. The neurons, are being stimulated and dumping into the synaptic cleft to connect the power of thought to the motion of the body. I had forgotten something about how the mind works, in fact how our whole nervous system works. As I pondered it again it seems so amazing.
I never bought another American car after that until they made Japanese cars here. ( To Ford’s credit we did like the 15 passenger vans though and they were great and reliable.) I thought I would never buy another new car either but 14 years later I did. It was a 2000 Altima. (I traded in an old Lexus LS 400) The Altima turned out to be a great car and passed on through my kids for many years. My son that had it bought a new Altima in 07 when he was done with that one.
Non-religious or non-spiritual people do find purpose in pursuing objectives related to their bodies and minds even if it is temporary in nature as opposed to eternal. Some are content to leave any spiritual connotations on a shelf and wait.
My preference is to understand how the spirit connects and have a complete experience rather than just a partial participation in what lays inside us, around us and even beyond us. If we don't develop our eternal selves then we will fall short in what has the greatest potential for happiness. That is eternal relationships with our families and the fellowship of exalted beings forever helping others through the stages of eternal personal development.
