Mercury affects the transmission of information from one point to another, thereby aiding or interfering with the thought process, communications, technology and travel. When Mercury is in an aspect to another planet, it tends to take on the nature of that planet, acting as a messenger conveying its energies. During its thrice yearly retrogrades, it triggers and reveals problems with communication, thought patterns, technology and travel. Mercury is considered neither benefic nor malefic, and moves through the zodiac in roughly one year.
