Mercury in 10th House
The 12 Houses of astrology are symbolic of the all the departments that make up human life. The planets and zodiac signs will manifest themselves most strongly in the sphere of life represented by the House in which they fall on your chart. Houses are not "energies" like the elements or planets, nor do they color the expression of energies like the zodiac signs do. The houses are WHERE these energies are most likely to manifest. The houses are the fields of experience, not the experience themselves.
