// Planet in Sign-M.Heindel-prepared G. Pentidis
Mercury in Aries :
makes the person very argumentative, fond of disputes, quick at repartee, with a tendency to exaggerate though not necessarily by design. If well-aspected he is broad minded and tolerant of the opinions of others, of a studious nature, quick to grasp situations and ideas, neat and orderly. When afflicted Mercury in Aries makes people leap before they look, the mind is vacillating and there is a general recklessness about the person who is thus very unreliable and devoid of all sense of responsibility.
Mercury in Taurus :
gives a mind that is not very soon made up but when it has once arrive at a conclusion it is almost as difficult to change as the laws of the Medes and Persians. However, being based upon thought and reason the judgment of these people is also extremely reliable. They believe thoroughly in the ancient adage that "Silence is golden" and are therefore close-mouthed. They are good counselors and can be depended upon to keep secret. At the same time they are not recluses, but have a pleasant, sociable disposition. They are fond of fun and recreation, they love music, art and literature, so they are thoroughly likable people if Mercury is well-aspected. But if Mercury is afflicted they become what the Scotch call "DOUR," also obstinate, stubborn, secretive and avaricious.
Mercury in Gemini :
makes a person fond of change and travel. He is always ready to investigate some new thing, or go to some other place for a change; in short, almost anything that is new appeals to him. At the same time if Mercury is well-fortified such people gain greatly by this fluidic state of the mind for they are shrewd and penetrating in their judgment so that they know good value when they see it and are not prejudiced by preconceived, set opinions. Therefore they are good business men and their ability to see a point makes them particularly good lawyers. They also succeed well as traveling salesmen.
Mercury in Cancer :
gives a clear intellect, a good memory and superlative adaptability. People with this position fit into any place or occupation they may find and adapt themselves to the opinions and ideas of others. They love praise and flattery, therefore they are careful not to do anything whereby they may forfeit the good opinion of others.
Mercury in Leo :
gives high ideals and aspirations, a positive, strong and persevering intellect which scorns to stoop to low and mean acts, and despises equivocation; is blunt and out-spoken, quick-tempered, but kind-hearted and sympathetic. People with Mercury in Leo well-fortified have good organizing ability and make capable leaders. They love children and are also fond of pleasure. When Mercury is afflicted in Leo it makes the person fickle and inconstant in his affections, an unsuccessful gambler and speculator, a low and sensual nature.
Mercury in Virgo :
is at the zenith of his power for there he is exalted, consequently when well-aspected it gives a clear, logical, scientific mind, eloquence and the ability to express oneself fluently in a number of languages. It gives the person a comprehensive, discriminating outlook upon life, his conclusions are usually practical and to the point because he also, like the Taurean Mercury, looks before he leaps. In short this characteristic is in a degree true of all the earthy signs. When Mercury is afflicted in Virgo it makes the man irritable, petulant and selfish, always looking for flaws in everything he comes across. People with Mercury in Virgo make excellent dietitians and chemists. They also have an unusual dexterity.
Mercury in Libra :
when well-aspected gives a broad, well-balanced mind with a love of art and music and an uncommon ability of expression. It brings success as a public speaker and sometimes as a singer. When Mercury is afflicted in Libra it indicates trouble by lawsuits through partnerships and an unfaithful marriage partner.
Mercury in Scorpio :
gives a shrewd mind, a keen aspiration, a quick wit and a sharp tongue with biting sarcasm that can sting like the scorpion. The disposition is bold and stubborn, headstrong and difficult to get along wit. But these people are extremely resourceful, dauntless, and able to overcome difficulties which would crush others. They are attracted to the occult, as a needle is drawn to a magnet. When Mercury is afflicted they are subject to disappointment in everything they undertake, quarrelsome, skeptical and cynical, always holding opposite views to others.
Mercury in Sagittarius :
Though in detriment it is still a strong position of Mercury and if he is well-aspected it gives an exceedingly noble mind of a religious and philosophical turn, a mind which scorns the shackles of conventions where they interfere with freedom of thought and speech yet does not fly into paths that are contrary to the commonly accepted standards of moral usage and conduct. It always confines itself within the boundaries of law and order and people with Mercury in this position are therefore greatly respected in the community. Mercury in Sagittarius makes the person fond of travel to see the sights and scenery of nature and to investigate the customs of strange people. He is also fond of animals and pets. When afflicted it inclines to lawlessness, dishonesty, sophism and a twisted character.
Mercury in Capricorn :
gives a critical and penetrating but somewhat suspicious mind with a thoughtful and diplomatic disposition, These people make splendid spies and detectives, having the ability to ferret out secrets in the most uncanny manner. They also have the persistence of Saturnians derived from the sign Capricorn so that they never give up until their object has been attained. This position gives a love of science, particularly chemistry. These people are much attracted to the occult, yet are practical and very thrifty. They hold on to what they get and always have something for a rainy day. When afflicted Mercury in Capricorn makes the person miserly, cruel, hard, malicious, vindictive and spiteful.
Mercury in Aquarius :
gives the Uranian qualities of originality and independence and an unconquerable love of liberty to the mind so that people with Mercury in this position are apt to repudiate all the social conventions and live according to their highly idealistic conceptions. They often take no heed of fashion, and dress in a style entirely their own. They advocate ideas on social subjects which are a thousand years ahead of the world's development, among them the theory of soul-mates and affinities which is causing so much trouble in the world today because it advocates have not yet grown to the spiritual stature where they can separate it from sex and live the true Uranian love-life which is altogether spiritual. The foregoing delineations apply particularly where Mercury is aspected by Uranus and the people described by them are the extreme product of Mercury in Aquarius. All who have this position, however, are very intellectual, they have high ideals and aspirations, a love of popular science and mathematics and are usually attracted to the occult sciences also, especially to astrology, for they have a fine faculty for reading the horoscope. They are kind, sociable and fond of friends with the result that they usually attract large numbers of intellectual people to their circle of acquaintances. When afflicted this position makes the person disloyal and ready to prey upon his friends, or criticize and slander them.
Mercury in Pisces :
the occult water sign, seems to endow the mind with a certain psychic faculty which is not so much intuition as imagination. They think or imagine that something must be so and so and it is a startling fact that they are usually correct, but this ability brings them dangerously near to mediumship if Mercury is afflicted or when Neptune, the higher octave of Mercury, is in the Twelfth House. Therefore this is rather a dangerous position. If Mercury is afflicted by Saturn this position in Pisces makes the person liable to gloom and the mind will be subject to constant worry with a turn toward melancholy. Usually, people with Mercury in Pisces are of a kindly and benevolent disposition. This also is a good indication that success may be attained in chemistry and as a dietitian in the preparation of health foods.
