one of the far too often "neglected" points of the chart when looking at the BIG "why"
is the I.C. -- Immum Coeli, the 4th House Cusp
this is a very important point in "karmic astrology" and is related, quite dramatically, to karmic patterns
people with planets closely conjuncting the I.C. on the 4th House side (use a 2-3 degree orb only) will often have a certain unconscious "fixation" in how they "deal"
the MC at the top gets most of the attention, but people who have planets prominently parked in the 4th House right on the IC (as I do: Retrograde Pluto in Leo less than a degree away from an exact conjunction)
often have both a "driven" and somewhat "Fated" quality to their lives
people with planets in the 12th closely conjuncting the Ascendant also have a strong unconscious driver in their psyche, due to "past life" influences, although with 12th House placements, these are often more "unconscious" and related to some type of psychological trauma
as a result, these are often individuals who are attempting to "compensate" for a wound, typically inflicted in early childhood
with the IC, it is different; these are individuals who start off in the Underworld . . . the worlds, above and below, "blend"
it is fascinating, too, how many of the most significant romantic relationships in my life have also had a strong conjunction from the 4th House on the IC
Astrology tells all; it just whispers
