Volatile and changeable, it takes on the most variable shapes and characteristics.
People with MERCURY well aspected on the chart tend to be very cerebral, deductive and rational. Our culture is very mercurial, as knowledge acquired from the outside in is highly valued.
Mercurial energy also comes to us through radio, television and newspaper waves. With MERCURY we learn not only how to communicate, but also how we communicate, including vocal timbre and hand and body movements as we speak. People with mercurial aspects gesticulate a lot when they talk.
With MERCURY we experience how important it is to communicate, because in every speech, silence or thought, we are leaving our message to the world, which will certainly give us its return.
