What does the eastern point in the astrolabe represent?

An astrolabe is a celestial map obtained from a certain position on the earth at a certain moment. It conveys infinite information to us through the combination of stars, phases, constellations and houses. Take the horoscope as an example. A person's horoscope is the horoscope captured from the latitude and longitude of his birthplace at the moment of his birth. It brings together the information of the owner's physical condition, psychological tendency, personality and emotion, spiritual ideal, interest and ability, and also points out the general trend and mental journey of most people's lives.

The stars on the astrolabe include the ten familiar main stars of the solar system (sun, moon, water, gold, fire, wood, earth, sky, sea and ghosts), and some imaginary points that will be involved (not stars, but position points calculated by a specific formula with mathematical methods), such as the north-south intersection of the moon axis (that is, Du Ji and Sizheng mentioned in Seven Politics and Four Politics). Lilith in the dark moon ... minor stars (asteroid belt between civil engineering) such as Kai Long Xing, Ceres, Poseidon, Pallas Athena, Vesta, virtual stars named after Greek and Roman gods, Cupid, Hades, Zeus, Cronius, Apollo, Ade Mentus, Fo canas, Poseidon, Prosepina, etc. can all be turned on with Astrolog32 software. The position of each star in this picture represents different sides of the owners of different sizes of optical discs. It can be seen that everyone is three-dimensional, and it is also a three-dimensional with countless large and small sides, scattering different forces brought by the stars. The angles between the stars in the astrolabe are called congruence (0 degrees), arch (120 degrees), Liuhe (60 degrees), punishment (90 degrees) and impulse (180 degrees), which are the most basic, including 30 degrees, 45 degrees and 150 degrees. This determines whether the forces of different stars are tense or harmonious, cooperative or antagonistic, dyeing or containing each other, which brings flexible vitality and infinite variables to the astrolabe. From the individual's point of view, the stage reflects the interaction between itself and the outside world. From a macro point of view, in fact, this paradigm of western astrology is based on constellation 12 and house 12. 12 is a wonderful number. Mathematically speaking, it is the least common multiple of 2, 3 and 4. The number 2 represents yin and yang, which are two extremes and two foundations; In the philosophy of Laozi, a great philosopher in ancient China, there is a saying that everything is born with three, which coincides with the division of three groups and four main palaces into basic, fixed and changing in western astrology. The number 3 is the law and process of the growth and development of all things; 4 represents the four elements of Tierra del Fuego's geomantic omen and the cycle of the four seasons, which means that it will bite itself with the first two and merge into a double roulette wheel arranged counterclockwise in the 12 area. It is also the tacit understanding between us humans and the rhythm of the universe.
