In my old volume,
The Best of the Illustrated National Astrological Journal 1933-4, picked up in an antique store some years ago, there's a rather odd article by Augusta Foss Heindel, wife of
Max Heindel occultist, astrologer and mystic. The piece is titled:
"Air Age Tests Human Heart....Noted Astro-diagnostician sees changes in heart due to Aquarian Age influence"
1933 - Aquarian Age? I think not. By some astrologers' calculations we are still, even in 2014, nowhere near the Age of Aquarius, even though that label does fit the current Age - as we see it, not as proper calculation would define it. Maybe people have been willing on the Age of Aquarius since an astrologer first came up with the concept.
Still, laying aside argument about astrological Ages, here are a few excerpts from what the author proposed:
She began:
We are entering an "air" age! On every side we see evidence of this fact. Several years ago an advertising man of Colorado coined the term "air-minded"; daring men conquered oceans with airplanes; millions of dollars flooded into the industry of aeronautics; air mail, air passengers and even air freight were discussed by everyone................It is evident that the public has definitely "accepted" aviation and is building toward an "air" future.
The author goes on to explain why this should be....
We know that the earth itself advances in direct relation to the precession of the equinoxes. And we are now entering into the airy, electrical and etheric sign Aquarius, During this age men must conquer the air and ethers which surround the earth.
That brings me to a point bearing upon man himself. To conquer the air, man's physical body must undergo some changes. Just as Lemurian and early Atlantean men had to develop lungs in order to breathe the clearer atmosphere, so must man now develop organs which will enable him to fulfill the divine plan.
There are two organs undergoing this evolutionary change, the eyes and the heart. The eyes must adjust themselves to become responsive to a higher octave of vision, and the heart must develop "cross stripes" or muscles which will be more easily controlled by mental process. It is interesting to note that eye and heart tests are the outstanding tests in the physical examinations of airplane pilots..................Eye and heart trouble are prevalent now because of these changes which are taking place.........greater number of people, especially young people (are) wearing glasses........The development which is taking place in these two organs has become more perceptible since the planet Neptune transited the heart sign Leo, which occurs only once every 168 years, September 1914 marked the beginning of this transit and since that time heart ailments have increased tremendously.......................
She continues about astrological diagnosis in health care generally.
While I took most of what the author had written with a hefty pinch of salt, I did begin trying to relate her ideas to today's world. Do we need some modification physically to cope with our digital age/ technologial age/virtual age/social-networking age?
Leo rules the heart, according to astrological lore; Mrs Heindel's words were written during a Neptune transit of Leo. Neptune currently, in 2014, transits Pisces, sign of its own rulership. I see no connection to the digital age. A better connection would be Neptune's Aquarius transit, 1998 - 2012. We'd entered the computer age in general some decades earlier than that, but personal computer use and the internet took off on a far wider scale during that time span. Anatomically Aquarius relates to the shins and ankles, and, via its traditional ruler Saturn, to the bones, teeth, joints and skeletal structure.

I cannot see the same kind of connection Mrs Heindel made between the heart, Leo and the "air age". Current human physicality in need of development to better match our digital age would be in the brain's realm, which is ruled by Mercury, whose home signs are Gemini and Virgo. Currently no planet transits, but Saturn, traditional ruler of Aquarius, has transited both signs since 2000: 2001-3 for Gemini and 2007-9 for Virgo.
Are we humans in for some evolutionary modification, mentally, to cope with this digital age? Did humans really need heart and eye strengthening in order to deal with the "air age", which of course went on to develop into "the space age"? Flyers managed well enough with basic aircraft, but once speed barriers were broken, and space travel became a possibility, from there on, I guess only the strongest were chosen to take part. So...perhaps following a similar pattern, to date in the digital age's early stages, we've coped well enough with new technology, but coming decades could prove that we shall not be able to cope with anything more complex without a touch of evolutionary physical modification.
