General information about Mercury in your birth chart

The presence of Mercury in the birth chart serves to determine how people communicate. Therefore, this is conditioned to the house occupied by the planet as well as to the sign present in this house, since Mercury is very adaptable.

The planet focuses on mental aspects and is responsible for commanding the means of expression, from speech to writing. It also commands transportation activities due to the speed with which it moves and is associated with routine, especially the obstacles encountered in daily life.

Mercury and communication

All communicative processes in a person's life are commanded by Mercury. This is the planet of expression and it can appear in different ways for each native. Also, it is worth mentioning that it is not only connected to speech, but to any kind of mental process and, therefore, even the construction of thought depends on Mercury.

So its positioning can make people intellectually arrogant when the planet is in tension, but it can also make them idealistic if the crescent is sharp.

Versatility and inquisitive nature

It is possible to state that Mercury is a planet of many faces. The way it is expressed in the birth chart depends on a series of connections with other factors, ranging from the accentuation in the parts of its symbol to its positioning in the astrological houses.

This is a planet of inquisitive nature and very questioning. This is because Mercury connects the super-conscious, the unconscious and the conscious as human beings relate to each other. It also commands routine and its obstacles.

Mythologies and symbols associated with Mercury

In Roman mythology, Mercury is associated with Hermes, the messenger of the gods and the one responsible for making the connection between matter and spirit. Therefore, all processes linked to the nervous system are the responsibility of this planet, which operates as a link between a person's inner universe and the external world.

The glyph associated with Mercury is formed by a cross, a circle and a crescent, which can determine the native's behavior according to the most accentuated part.

Areas of life ruled by Mercury

Mercury is domiciled in the 3rd and 6th houses of the astrological chart, which correspond, respectively, to Gemini and Virgo, the signs it rules. Thus, the areas of life ruled by the planet are communication, represented by the 3rd house, and routine, represented by the 6th house.

So, besides talking about the ways someone expresses himself, Mercury also determines the relationship of this person with his work, something which is very important for the sign of Virgo. Thus, the planet is responsible for commanding practical attitudes.

Signs of dignity, exaltation detriment and fall

Mercury Inconjunctions

The inconjunctions of Mercury are the signs that do not share anything with this planet and are opposite to it.

So, it is necessary to have more detailed information to be able to determine the inconjunctions accurately.

Mercury Retrograde for Astrology

In certain periods, the planets and celestial bodies move differently in the sky. Therefore, this change causes slowness in their cycles and makes one have the impression that they are moving backwards - hence the name retrograde motion.

This movement is part of the course of all planets except the Sun and the Moon. When we talk about Mercury, this movement affects the life of all people, regardless of their birth chart. Thus, the planet's transit makes some people more sensitive and generates wear and tear in communication.

To know more, continue reading the article and find more details of Mercury's retrograde motion.

The Retrograde Planets in the Birth Chart

With the exception of the Sun and the Moon, all planets present in the birth chart make retrograde movements. Energies are felt more intensely and in many different ways, which can stimulate characteristics such as introspection and make natives more uncomfortable, easily embarrassed.

This all depends on which planet is initiating this movement, as each one alters a different area of life. For example, Saturn retrograde can cause a lack of discipline and structure in the native's life, making them uncomfortable to follow rules.

Personality of Mercury Retrograde

Mercury is the ruling planet of the nervous system, so when it goes into retrograde motion, all mental and communication processes, from listening to the ability to research, are automatically affected. This can also affect electronic means of communication such as smartphones and computers.

Therefore, the period calls for review and concentration. There is something important to do and actions like cleaning up the work environment can help you get through this phase more smoothly. In addition, Mercury retrograde also calls for some form of rest.

Mercury Retrograde Karma

Mercury Retrograde's karma is linked to communication difficulties, so it can come to cause disruptions in this milieu and damage a number of means of expression, so this period should be used for re-evaluation of various issues while the transit takes place.

Thus, during transit, it is interesting to take some time to think about the way you have been positioning yourself and dialoguing with others. Doing so may help you realize new avenues of dialogue that have not yet been explored and may be interesting.

Which signs are ruled by Mercury in Astrology?

The signs ruled by Mercury are Gemini and Virgo. In the case of the first sign, the influence of the ruler is in the sense of sharpening curiosity. Thus, natives need to know a little about everything that exists in the world and want to learn as much as possible, something that can cause them to lack focus.

Thus, they are people who disperse easily and tend not to continue their projects because they are interested in other things. This process is not repeated with the sign of Virgo, in which Mercury acts differently.

As far as this sign is concerned, the planet makes the native's mind very analytical and he has the ability to reason in a practical way. Therefore, the native likes accuracy and has very keen minds.
