Planetary Stations in Vedic Astrology are very important. Before planets change directions they appear to completely stop in the sky.
This is called a “Station”,.. and show energy concentrated and not moving. This shows where are stuck at a certain time .. either ready move backward or forward.
In a natal chart this is also important and shows energies that are stuck.
Planets are “stationary retrograde” before they go backward. Then “stationary direct” before they go forward again. The outer planets (Mars, Saturn and Jupiter) can station, or slow down dramatically, for a month at a time or more.
