The Sun is the individual's ego, his aspirations, his inner self and his will, that which he tends to really be, unlike the Ascendant which is the image projected onto others. The Sun is the masculine part of the personality, the Yang, and as such, he represents all male figures (father, husband, leader, etc.). He provides clues to the image of the father and men in general, as well as the type of relationship with them, regardless of the gender of the chart's owner. However, he seems to be more important in men's chart, since he stands for all masculine and positive values. The Sun is a star of warmth, life, and light. Therefore, he emphasizes courage, loyalty, nobleness and generosity, but also pride, irascibility, and self-centredness. In a woman's chart, the Sun usually symbolizes her father, and later on, her husband. The Sun is always active in the woman's personality and represents her ideal of man. The Sun is associated with youth, the period in life when, brimming with ambitions and hopes, one completes one's studies.
The Moon is complementary to the Sun in the sense that she represents the feminine part of the personality (the Yin), the unconscious, the emotions and the sensitivity of the chart's owner. She symbolizes all feminine figures such as the mother, the wife, etc. She is a sign of fertility, femininity, imagination and memory, or lack of, depending on the aspects she receives. She is particularly important in a woman's chart because she is believed to express more or less easily her female status and her femininity. In a man's chart, although the Moon represents his sensitivity, she may be of a lesser importance, since she is often repressed. In addition, she symbolizes the chart owner's mother, and later on, his wife as well as his representation of the ideal woman. The Moon is the night star. Therefore, she is associated with dreams, the unconscious, subjectivity, moods, the past, nostalgia, but also with laziness, nonchalance and whims. Besides, she is of utmost importance for children, because they have not yet learnt to master their primary instincts, and remain very attached to their mother.
The position of the celestial bodies, as seen from the Earth and the place of birth, is established in connection with a system of coordinates based on the horizon and the zenith. For each astrological chart, the time and place of birth are processed in order to get markers that are specific to the individual. This is how it becomes possible to materialize the positions of the planets, the Sun, and the Moon in the window of heaven known as the Zodiac. The celestial belt where the Sun relentlessly follows his course, when seen from the Earth, is divided into twelve equal parts called zodiacal signs. It all works out as if all the human features were represented within the whole twelve signs. Each sign reflects an independent and strong typology, complementary to the other signs, expressing by itself its nature and its personality with its characteristics, its tendencies and its motivations.
