Should Buddhan be in the lagna, the person will be educated, be married early (whether legally or symbolically), will intently learn the scriptures and listen to their recitation, will be inclined towards tantra vidya and will either be an exorcist or will have the power of one. The person will be a healer. The person will have a soft, forgiving, and kind heart; they will have enormous gains of wealth and will receive academic recognition at the age of 27. They will also go on a pilgrimage or spiritual quest at this age. If conjunct with a malefic or in the house of a malefic (Mars, Saturn), the native becomes subject to skin diseases, bilious troubles, and there will be a slightly yellowish tinge to the skin; if associated or in the house of a benefic (Venus, Jupiter), however, the native enjoys good health. If both conditions are there, then the health effects may be present but in small/unbothered quantities. The native’s body will have a golden aura and they will take an interest in astrology; however, they will have a defective limb (or a neurological disorder), will hate men, especially wealthy men, and will suffer from eye troubles. The person holds anger towards their brothers in their 17th year and commits an act of deceit. This does not last if Mercury is in a friendly sign (Libra, Taurus, Leo), let alone in its own (Virgo, Gemini) or exaltation (Virgo). In all of these conditions, the person attains Heaven after death, will be religious-minded, and well-versed in weaponry. They will also have a perfect body (not too far nor thin), will be knowledgeable in logic and arithmetic (i.e., they will make good accountants, financial analysts), and if aspected by Rahu, the person will be a mathematician or a statistician by capability.
If associated or aspected by a malefic or in the sign of debilitation, the native will worship tantrik deities, will have knowledge of the dark arts, and be deprived of sexual comforts. The person will have a wild mind with uncontrollable excitement and will always be against those who they don’t like. They may forget things and commitments/statements. They show off, will do things in a highly secretive way, and have the ability to organize any kind of conspiracy for the downfall of someone they hate. It doesn’t mean that they will do it — it means they can. If there is absolutely no benefic influence (i.e., in the house of a benefic, aspect of a benefic), the native goes to Hell for practicing the dark arts. If conjunct with a hard malefic (e.g., Saturn), the person loses sight in their left eye. If conjunct with the lord of the 6th or a debilitated planet, the person goes into debt because of undeserving and unworthy people. The native gives money to such people out of sympathy.
More general effects include: the person speaks with sweetness and tact, they are long-lived, and very intelligent, even brilliant depending on the horoscope. If Mercury is retrograde and combust, the person is a genius, but they will have a problem verbally expressing their thoughts due to overthinking about tactfulness, especially if conjunct with the Sun. They will also get bored easily. They earn their living through some kind of written work and will be highly skilled as a physician, even if they are not formally trained in medicine. Mercury in the lagna destroys Arishta caused by other graha in the horoscope.
The native will be young-looking and will have some childish feature to their personality and body. They are good at multi-tasking, are polymaths, and they pick up information very quickly if taught orally. They are good at poetry as well. The person additionally has good administration skills, especially if Mercury is posited in Taurus, Libra, or Leo. They will especially be adept at influencing others like a king or queen.
They are knowers of the beneficial place and time for any event. If Mercury and Sun are conjunct or in a direct aspect, the legally married spouse of the person will be good-natured and from a rich and noble family. The native themselves will gain massive wealth within a short period of time and will have many sources of income if the Sun is in the 1st house; otherwise, the relatives represented by the house in which the Sun is placed will have this condition.
The in-laws and children of the native will be adverse. The natives, despite being of sattvic nature, may take a special liking to non-vegetarian food and elaborate drinks. The person becomes a devotee of Vishnu or Lord Vishnu in some way helps that person. The natives themselves reflect aspects of Vishnu, as if they are an avatar. The hands of the person will be slender and they will have an average to tall height. They will have dark, intense or expressive eyes, with curved, thick eyebrows and will walk quickly. They can learn without a teacher or guru.
