Hi,
I can't see a chart through the link you provided.
Having a grand trine in Earth usually means that there is an inherent 'foundation' that is built upon all that is experienced as physically tangible of nature.
Venus would relate to perceiving the pleasures in life through the manifested reality of Capricorn: permanent and Protectively defending, coolly limited and restrictive, or icily distant.
Mars in Virgo is 'mechanical' of nature. Everything must work perfectly together like every individual part of a machine .....or the physical body
. If there is any kind of spoke in the wheel (through harsh aspects), the natural working process can be affected.
Chiron in Taurus would probably show 'how' one's attitude is towards what it physically has .... or doesn't have. It is strongly associated with the effect of 'inner pain' caused by others, that one lives with. Observation has shown that the internal scars from that pain can often see a comparison with outer physical scars through accident, surgery, etc.etc, and even self harm.
Dermatoligical skin allergies can find an association with Moon in harsh aspect to Virgo. Skin eruptions could well see Mars at work.
Self awareness has been said to awaken around 7 years, when the child begins to recognise the Mars 'me, me, me (tantrums)' which begins to emphasise its separate distinction from mother ....the Moon in a chart.
Anorexia and bulima have strong associations with Moon to Neptune and/or Pluto.
Bullying can be applied to Pluto as well. If there is a harsh aspect between Mars- Pluto, this can turn physical as well as having a mental/emotional affect.
Hair falls under Capricorn. 'Beauty' of it brings in Venus.
Observation has also shown that surgical scars see a relevance of inner pain scars transposed into physical ones, as per situations an individual is not able to deal with.
Jupiter relates to positive good health. Generally speaking, Jupiter in harsh aspect can show where there are 'issues' in this direction.
Any 1st house position deals with the personality and its effect upon the physical constitution.
A 1st-5th-9th house association would show the relevance of living through and for one's self via one's own personal convictions. Not always easy if outer circumstances have more power than lie within one's self to combat them. Yet, with Earth the inherent physical strength
is always available.
If there are harsh aspects to the grand trine in Earth from other planets in their signs, their functional traits per sign will show the conflicting challenges to face for those which are inherently as solid as a rock.... whichever way one cares to looks at, and/or experience it:E.g. that which holds one back from moving on, or serves to protect when doing so.
