Mercury transits show where mind and speech are most active for the time being. These transits are quick, but not unimportant. You may notice things get busy wherever Mercury is active in your chart. When Mercury is retrograde, beware of making rash decisions or purchases. Many people find a retrograde period is best used to review work done before.
Planet Mercury is connected with the sun. While the sun rules the mind and ego, Mercury describes how you communicate what goes on in your mind. Thus, it is connected with speech, writing, and motor skills. Robert Hand reminds us that Mercury is also the planet of pranks, so keep that in mind.
The way Mercury works depends a lot on whether it is afflicted or supported by other factors in the chart. If afflicted, it causes confusion, pessimism, worry, deception, etc. If well-sapected or if there are supporting transits, it brings clarity of mind, quick-thinking, versatility, cleverness and mental energy.
