When someone speaks of being a "double
Scorpio" (actually any sign of the Zodiac could be substituted
for Scorpio) it is another way of saying that both the Sun and The
Moon were in the same Sign at the moment of birth. This would
always happen for a birth exactly at the New Moon, for example, and on
either side of the New Moon for the period of time that the Moon remains
in the same sign as the Sun.
The birth (natal) chart would show that the Sun and the
Moon share the same Sign -- Scorpio in our example. The
implications of such an arrangement would be a relatively congruous
combination of the anticipated energies.
The Sign placement of the Sun suggests the general
energetic focus of life purpose, the end to which we feel
driven. The Moon represents the character of our psychological needs
-- what we need on an emotional level in order to feel fulfilled.
So when we have both the Luminaries (the Sun and
the Moon) in the same Zodiac Sign, we would expect a highly focused
energy, a relatively well-defined direction that the individual will be
inclined to follow during his or her lifetime.
Returning again to our Scorpio example, we would
anticipate that the individual would use their energy in an intense
pursuit of knowledge and control and would probably experience
extreme peaks and valleys along the way. Emotionally, intense is
again the operative word. Needing to be in control and make an
emotional impact is so important.
When the Luminaries share the same sign, we see arguably
the two most important points in the Horoscope operating along very much
the same lines. It gives us a sense of relatively "pure"
astrological energies.
For a moment, let's pretend hypothetically that an
individual existed where not just the Sun and the Moon, but ALL THE
PLANETS were in the same sign. Whatever that Sign, can you imagine
that the focus would be so extreme without the opportunity to tone down,
complement, or balance some of this extreme emphasis with other components
of the chart.
One of the astrologer's jobs is to help the client
integrate all the individual tendencies and motivations into the strongest
and most productive combination of influences consistent with their
potential.
Note: When someone says that they're a "Triple
Scorpio", not just the Sun and the Moon, but also the Ascendant
(the Rising Sign) are in the same Sign, in this case
Scorpio.
