Mercury is the planet of knowledge, intelligence, active speech and writing. The well-expressed principle of this luminary imparts to people a love of travel, acquaintance and communication. From this point of view, the finding of Mercury in the 9th house is successful, because this house is associated with higher education, that is, with the development of a person's intellectual potential.

MERCURY IN THE NINTH HOUSE and well-aspected gives love of religion, science, letters and law, a studious mind capable of delving deeply into profound problems of life and being, philosophic and philanthropic tendencies, and desire to travel far if need be in the pursuit of knowledge.
This position gives facility in speech and writing and success in religion, philosophy, law or science. The mind is broad, flexible and adaptable, therefore the person is liable to change his views several times in his life on the various subjects which he has studied, but there will always be a good reason for adopting another viewpoint.
If Mercury is afflicted in the Ninth House he makes the person exceedingly unstable of mind, changeable as a weather vane in all his pursuits and activities. Such a person will never stay by anything long enough to try it out and therefore he will meet with a series of disasters all through life. Probably he may journey from one place to another in search of success but he will never find it until he learns to concentrate his energies upon one thing. This position is also a fruitful source of trouble with the law or legal affairs.
