Retrograde planets in a birth chart, not the news kind

Everyone has heard of Mercury retrograde as a passing event. Fewer people know that if a planet was retrograde at your birth, it stays that way in your chart for life.

What retrograde actually is

Nothing goes backwards. Retrograde is apparent motion: from Earth, an outer planet appears to reverse for a while as we overtake it. It is a perspective effect, and it is completely predictable.

Natal retrogrades

Around one person in five has Mercury retrograde natally, and outer planets are retrograde a large fraction of the time, so retrogrades are common rather than exotic.

The traditional reading is internalisation. A natal retrograde planet does its work inwardly first, and often out of step with how the person is expected to do it. Mercury retrograde at birth frequently describes someone who thinks slowly and thoroughly and is misread as slow, then turns out to have understood it better.

What it is not

It is not damage, and it is not weakness. It describes a different route to the same function.

The Vedic reversal

This is one of the places the two traditions genuinely disagree. Vedic astrology often treats a retrograde graha as strengthened, not weakened, on the reasoning that it is closest to Earth and brightest at that point. A Western reading of introversion and a Vedic reading of added force can both be describing the same planet.
