Receptions! Receptions! Receptions!
Look at the dignities of the luminaries, and see if any of those planets are also in the dignities of the Sun and the Moon. If you find that either of the luminaries are in beneficial reception, mixed or mutual, with another planet, and if this planet has dignity, then this describes the influence that can pull the detrimented planet out of it's unfortunate position.
There are few charts in which a badly debilitated planet has no other strength to draw upon from elsewhere in the chart via the web of receptions.
Receptions are completely ignored in most astrology today, and astrology is so very much the poorer because of it, but it doesn't need to be.
In fact, a debilitated planet does not have to be in actual reception to derive benefit from another planet, it's just better if the planet to which the detrimented planet appeals takes some interest in it's plight.
For example, I have a peregrine Mercury in Libra, but fortunately, it isn't all so bad for Mercury, as Mercury exalts Saturn, and Saturn is also in Libra and is in Mercury's term, so Saturn takes a bit of interest in Mercury's situation, and so is inclined to respond to Mercury's appeal for help via the mixed reception. Saturn is able to help Mercury even more in that he is the Lord of the Geniture. So when my troublesome Mercury causes me to go askew in life, I know that I can draw upon my powerful Saturnian qualities, to kick Mercury's **** into gear. To derive benefit via receptions in this way however, usually requires will and concious application, if the two planets are in aspect however, the exchange is more automatic.
Astrobhadauria,
What does this mean? I am a Mars in Scorpio native.
True.
I disagree. You have just said yourself that a peregrine planet is a planet that does not have any essential dignities in it's placement, but this is certainly not equal to a planet that is as essentially undignified as it can possibly be.
A planet in it's peregrine state, it has been said, given the opportunity, tends towards malice. This is a far cry from being in detriment, or being comparable to detriment.
Lilly equates peregrination with detriment in that he gives each a numerical value of -5, but then, what is the point in making a distinction between the two debilities? I would agree with Frawley, who gives peregrination a value of -3, which makes more sense, because then we have a sliding scale of essential debility, detriment -5, fall -4 and peregrine -3.
Looking at it like this, peregrine is about as bad as triplicity is good.
Personally, I do wonder why, that if peregrination means 'no dignity', why it is not given a value of '0'.
Antikythera
The word 'peregrine', originates from the Latin 'pereger', meaning 'beyong the borders', and 'ager' meaning, 'land'. So a peregrine planet is literally a wanderer in an unfamiliar environment, outside of it's natural territory, and cannot relate to the position it is in.
A peregrine planet having no dignities of it's own, is strongly influenced by those planets with which it is configured, by aspect or reception. The lack of dignity of the peregrine state can be alleviated somewhat by accidental dignity, or by aspect or reception, preferably both, with a more essentially fortified planet.
