Understanding your natal chart, or that of another, can be simplified by a straightforward and fun exercise: assigning roles to each personal planet (the Sun, Moon, Mercury, Venus, and Mars) and imagining exactly how these individual “players” might get along inside us!
In a general sense, we can think of our Sun sign as our internal Adult. The Sun will listen to all of the other planets’ input, but the Sun is the boss of the one who screens the action. The Sun will send out different planets on different missions. For example, Mercury when it is time for expression, Venus on a date, Mars when action needs to be taken. However, the Sun is a person’s internal parent or adult, and few things get past him/her.
The Moon is our internal child. The Moon represents our feelings, often those that are difficult to put into words. When we are feeling and thinking one thing, and we are asked what is on our mind, more often than not, our Sun (adult) screens these feelings so that what comes out of our mouth is not quite the true emotions we have been feeling. Those difficult-to-express emotions and thoughts are our Moon, and what we let out of our systems is more often than not screened and refined by our Sun. How we express ourselves (the style in which we communicate), however, is ruled by our Mercury. Mercury does the talking and rules our more impersonal thought processes.
Venus can be seen as a more refined Moon. Venus expresses what makes us feel good, and is inspired when we are in partnership and romantic situations.
It also represents our lifestyle and public appearance.
Mars represents action. Our first active impulse is ruled by Mars. What fires us up, what gets us out of bed, and what lights our fire of these fall in the domain of Mars. Mars represents impulse and embodies our instinct for survival of the “fight or flight” instinct.
Mercury represents our Judgement. It also represents influencing factors on judgement like friends, relatives.
Even if a person has weak moon(mind), if he/she has a stronger and unafflicted mercury, they can make correct decisions and progress.
Jupiter is our knowledge. It represents what we take pride in, like our family, our social status, wealth, knowledge and qualifications we earn.
Jupiter also gives us values we apply in our society. It also represents our teachers.
It controls the knowledge, intuition and experience we use to apply our judgement.
Saturn is our honesty, humbleness, sincerity, patience, concentration and skill in our work.
It represents our nature of adjusting to the circumstances, working as an employee under someone, willingness to take orders, self discipline and hard working nature.
Saturn gives us concentration, energy and environment to do secluded work like writing, sculptures, meditation, spiritual journey, trekking of mountains, walking long distances by foot etc.
Rahu and Ketu represent our balance karma (prarabdha) which we have to face in this life.
While Rahu deals with all materialistic things and illegal activities like High personal Ego, Mafia, Smuggling, Gambling, Killer Instinct, criminal attitude etc, Ketu deals only with spiritual issues which are exactly opposite.
