Results of Mercury in 3rd House

The 3rd house is the natural home of Gemini, which is ruled by Mercury which makes it a harmonious zone for the considered planet. Moreover, the 3rd house is sharing the same significations with the planet Mercury, such as communication, entrepreneurship, commerce, publishing, crafts, and intelligence. As a result, the traits of the planet Mercury are highly amplified in the given house enabling strong effects (sometimes too much of the good thing).

Intelligent & Clever

Both, the 3rd house and Mercury signify mental intelligence. Accordingly, Mercury feels at home in this environment that the 3rd house offers to make the intelligence of Mercury prosper.

As a result, people with this combination are mentally very intelligent and smart in many topics and sciences. They are also very clever and know how to apply their knowledge base efficiently in order to move forward and prosper.

However, if Mercury or 3rd house lord is ill-placed, it lessens the amount of intelligence.

An undignified Mercury in the 3rd house also indicates using the wit and intelligence in unethical applications, such as on fraudulent schemes.

The bravery provided by the given combination helps to get things done no matter how adverse the situation may be. On this basis, it can be also concluded that a favorably placed Mercury in the given house blesses with mental stability and great emotional strength/intelligence.

Physically Fit

A well-placed Mercury in the 3rd house (of hobbies and activities) provides interests for physical activity which promotes becoming physically fit and healthy in life.

If Mercury and/or the 3rd house lord is unfavorably placed, it indicates being hesitant and lacking will-power and motivation to undertake heavy schedules of physical activity. It is important to note there as Mars is also signifying the 3rd house and fitness, it can save from the ill-effects of unfavorably placed Mercury in the given house.

For instance, when Mercury and the 3rd house is damaged, it initially creates a situation where the lack of physical activity is affecting the body and health negatively. However, eventually, with the help of strong Mars, a great comeback is indicated with the ability to successfully recover from the given ill-condition and gain back confidence, ambition, and will-power to succeed.


Both Mercury and the 3rd house signify communication, both written and verbal. This makes easy for Mercury to apply its communicative and information transfer abilities efficiently in this environment of the 3rd house.

As a result, this combination gives profound interest and desire to communicate and connect with people and thus creates a very communicative person.

In addition to verbal communication, these natives have natural interests and talents in the written form of transferring information, such as publishing, networking, telecommunications, etc.

Righteous & Moral

The energies of Mercury resonate harmoniously with the ones of the 3rd house and provides various great qualities to a considered person with this combination.

The direct (7th) aspect of Mercury upon the 9th house (of higher standards, morals, ethics) indicates being righteous, ethical, and moral. It also gives interest in philosophy and/or various other higher studies. Mercury also combines a touch of poetry with the philosophy which is expressed beautifully by the people with this combination.

In addition to that, this combination also indicates being detached from excessive worldly/materialistic attachments – in other words, this combination provides the ability to keep the desires under control which prevents from doing immoral or sinful deeds in the name of wealth.

Alternatively, if Mercury is ill-placed in the 3rd house, it indicates a lack of morals, ethics, and standards. If also 3rd lord is ill-placed, it indicates taking immoral measures for personal advantage because of selfishness. It also indicates a lack of self-confidence and lots of inner insecurities which is the prime reason for many unacceptable deeds and violation of morals.

Blessed with Siblings

Mercury and the 3rd house mutually share the significance of siblings. Accordingly, the given combination indicates having many brothers and/or sisters. If Mercury is well-placed, it also blesses with a great and harmonious relationship with them.

If either Mercury or 3rd house lord is unfavorably placed, it indicates disharmony in the relationship with the siblings.

Skilled & Hardworking

The 3rd house governs all types of craftwork made with skills of limbs while Mercury is the planet of strategy, with, and analytics.

Hence, the positioning of Mercury in this house makes the native naturally skilled, especially when it comes to the handicrafts or other talents in which limbs and tactics are considered as strengths.

However, the 3rd house is still a malefic house which means that the native must struggle hard and put in a lot of effort and hard work in order to succeed in their undertakings.

Entrepreneurial Interests

The 3rd house also belongs to the triangle of desires or Kama Trikona, in which the placement of Mercury, the planet of merchants provides profound interest in entrepreneurship and deep desire to establish a personal venture in order to express one’s intelligence, craftwork, and gain wealth.

Similarly, the combination indicates being restless and always desiring to accomplish something meaningful. That effect is provided by the fact that Mercury in the 3rd house casts direct aspect upon the 9th house of higher wisdom and meanings of life.

Classical Analysis

Bhrigu Sutras

According to this classical source, individuals with this combination will be very happy in the account of the number of siblings they have.

The given effect is provided by the fact that Mercury is a natural benefic planet and supports the significations of the 3rd house, such as siblings, positively in the given house enabling enjoyment, cooperation, and happiness with them.

It is also mentioned that Mercury is very auspicious regarding earnings in the 3rd house. That is because Mercury boosts the 3rd house with mental intelligence, strategic, and analytical ways of thinking which ultimately enables these natives to apply their effort to correct places, timings, and at the same time efficiently. This indeed enables them to earn great gains from their success regarding their talents and skills.

It is even mentioned that as early as in 15th of age, such natives acquire their first significant possession, which is earned by their own efforts. This is not necessarily earned in an actual job, it can be earned through good deeds or devotion to parents, for example.

Such natives are also said to have a lot of dignity, ethics, righteousness, and morals as per Bhrigu Sutras. These traits are provided by the aspect of Mercury upon the 9th house, which signifies all the same things.

As per thumb ruler of astrology, Mercury should be also dignified in the given house. Otherwise, it produces a highly hypocritical person.

A lot of importance is also given to the condition of the 3rd house ruler, which is the guide of Mercury in the 3rd house.

Namely, if the third house ruler is strong and dignified, it also boosts the good results of the given combination making the native very skillful, talented, intelligence, long-lived, valorous, and tolerant. The siblings of the native are also very skillful, strong, and courageous.

Otherwise, when the 3rd ruler is weak and undignified, it also decreases the outcomes of the given combination to some extent. As a result, the natives lack courage and impulse which makes them unable to take proper action in order to achieve their desires and aspirations. The siblings of the native are also negatively affected indicating struggles and lots of hard work for them.

Brihat Jataka

In this classical source, a negative case scenario is mentioned when Mercury is undignified in the given house.

There is mentioned that such natives are extremely clever and intelligent but harness it on deceitful acts.

Such an effect will not realize if Mercury is in good dignity and well placed in the given house.


According to this classical source, these individuals have the happiness of siblings and are very courageous.

There is also mentioned that these natives have to work extremely hard in order to reap rewards of their efforts and earn good gains. That is because the 3rd house is a malefic house which prompts the natives to work hard before succeeding.


In Saravali the same positive results are mentioned as in the previous sources. In addition to that, there are also mentioned that such natives lack friends and have a very restless mentality.

As per my view, the lack of friends is provided because the native spends most of their time on developing their skillsets and hard work. As a result, they have less interaction with friends circles which also decreases the number of friends they have.

On the other hand, such natives keep a close and tight local network for working purposes. These natives share common interests and talents with the members of their local network. By interacting with the members of their local circle, they are able to manage their time more efficiently and train their skillsets at the same time. By avoiding waste of energy on irrelevant side activities with other friends they become more successful as a result.

Chamatkara Chintamani

In this classical source, it is mentioned that such natives will be involved in local networks of successful entrepreneurs. As Mercury is the planet of merchants, they are naturally skilled entrepreneurs and have a desire to interact with people who have similar interests and talents.

When they surround themselves with such people, they become more skilled in what they do and eventually launch their own enterprise. That is because surroundings influence us in a great way and therefore we must always surround ourselves with people who have a good influence on us. These natives are naturally well aware of this and therefore keep their contact circle very small and specific in order to avoid distractions and negative energy.

At the same time, it is mentioned that such natives are free from worldly attachments or illusions and keep their eye steadily on their goal. They are very determined and never let anything distract them, especially friends or other people who try to bring the progress of the native to a halt.

There is also mentioned that siblings will be highly dependent on the native with this combination.
