In the last few hundred years or so - while accelerating decade by decade, such that in only a couple hundred years or so - life expectancy has more than doubled, technology has put men on the moon, and has produced smart wireless devices that can wrap around your ears and eyes, while your car drives itself - with humans as the passengers - to wherever you like.
BUT, the brain and the mind is made for much more than just altering the look and feel of this planet, increasing the number of objects that are mostly useless, and generating wealth for the fewest of the few, while the rest remain nearly in poverty. This extremely obvious fact, for some, has all but escaped most everyone such that their main examples of "personal achievement" has mostly to do with physical pursuits - building things, accumulating things, playing with things... things, Things and more THINGS!
The body is a great and wonderful thing, but it is nothing, NOTHING, without an Aim and a Wish. The body has been around for about 4 to 7 decades or so, give or take, and has been wandering around a VERY small patch of land for most, if not all of that time, but ask yourself, honestly, what do you have to "show for it" intellectually, spiritually? Do you spend most of your time thinking about yourself, your issues, your concerns, your irritations, OR are you actually beginning to investigate, and explore, and discover, and create that which only the Brain and Mind, governed by Aim and Wish can DO, even more than anything else you do, physically?
The Aim and the Wish were not "designed" (by D(esigne)r Who) for altering the planet, or the body, but for experiencing Higher Mind, which everyone has direct access to (by virtue of having been born of woman, as a result of the sperm & egg hookup sequence) even this instant, as you are reading these words, and thinking your thoughts about them.
Ask yourself, what do you have to "show for it," intellectually, spiritually, that you can demonstrate not only to yourself, but to others if asked, that ADVANCES your CHANCES of SUCCESS at This Thing you have embarked upon so many years or decades ago?
