Retrograde planet (Vakri)
A retrograde (vakri) planet appears to move backwards through the zodiac for a while, as seen from Earth. It is an optical effect of the orbits, and in Vedic astrology a retrograde planet is treated as strong, not weak.
Also known as: vakri graha
Planets never really reverse. When Earth overtakes an outer planet such as Saturn, or an inner planet such as Mercury passes between us and the Sun, the planet seems to slow, stand still (a station) and drift backwards for some weeks before moving forward again. Charts mark it with an R or the word “vakri”.
The Sun and Moon are never retrograde, while Rahu and Ketu move backwards almost all the time; for them it is normal motion. Mercury turns retrograde about three times a year, Venus every 18 months or so, Mars about every two years, and Jupiter and Saturn for around four months each year.
Classical texts give a retrograde planet full motional strength (cheshta bala), and some liken it to an exalted one. Its results can feel more intense, more inward or slower to arrive, with matters revisited before they settle. In your chart it is a nuance to read, not a problem to fear.
