Astrological wheel, or mandala, is a map of the space surrounding us at the time of our birth. The wheel is divided into twelve sections called houses — six houses in the sky above, six beneath the Earth below. These houses are numbered counterclockwise, starting with the 1st house and the direction east, on the left-hand side of the wheel. Planets in the heavens are placed on the chart wheel in the houses that correspond to where they actually are in the sky. Of the 12 houses, astrologers find the four most important are the one directly above our heads (10th), the one under our feet (4th), the one on the left and to the east (1st), and the one on the right and to the west (7th).
These four are called angular, because they mark the corners of the chart: south, north, east, and west.
Life continues after the birth moment. Astrologers watch the planets (as they continue on in the sky after a birth) move through the houses of the natal chart. Their movement is counterclockwise as they go from the upper hemisphere (houses 7-12), across the ascendant, (1st house cusp) into the lower hemisphere (houses 1-6), and on around.
In the astrological chart wheel, the planets are placed in their zodiac positions. The zodiac stretches in a circle through all 360 degrees of the surrounding sky, and this circle is divided into sections of 30 degrees — the familiar 12 signs. Planet positions are measured within signs by degrees, minutes, and seconds of circular arc. Each degree contains 60 minutes of arc and each minute of arc contains 60 seconds of arc. For example, I might tell you that my Moon (Moon at birth) is in the sign Taurus (2nd sign). More exactly it is in the 23rd degree of Taurus. It is actually at 23 degrees and 28 minutes of the sign Taurus.
The chart wheel is usually divided into 12 sections called houses. The houses are numbered (counterclockwise) from 1to 12. The pie-like lines that divide one house from the next are called house cusps. For example, the cusp of the 1st house is the horizontal line on the left-hand (east) side of the wheel.
Keep in mind that our Earth makes a complete turn on its axis once in 24 hours. The chart wheel represents the space surrounding where we were born. It is as if we were standing outside with the sky above us (upper part of chart) and the Earth beneath our feet (lower hemisphere). As the Earth turns, it brings each of the 360 degrees of the zodiac overhead (or to any part of the wheel) once in 24 hours — a new degree of the zodiac every four minutes.
As you can see, the astrological symbols for the planets have been placed in the part of the sky (the house) in which they were at the time of your birth. For example, if you were born in the daytime, then the symbol for the Sun will be somewhere in the upper half of the wheel. If you were born at noon, the sun would be almost right overhead or at the top of the chart, while if you were born at midnight it would be at the bottom (4th house) of the chart.
The wheel is also seen as two hemispheres — a top and a bottom. The upper part of the chart (houses 7-12) represents that part of the sky that was overhead and above the horizon at the time of our birth. It has to do with the world of thoughts, ideas, ideals, and planning. The lower hemisphere (houses 1-6) marks that part of the heavens that we have under us — and cannot see — below the horizon and on the other side of the Earth from us. It has to do with experiences, embodiments, incarnation, and so forth. In other word, the sky above and the Earth below.
The Wheel of Houses
The chart wheel or mandala of 12 houses can be seen as a circle, or cycle, with each house leading to the next house, and so on, in a counterclockwise direction. Let’s start at the very top of the wheel, the MC and the cusp of the 10th house.
10th House. The 10th house at the peak of the chart, represents the most ideal or out-of-the-body part of the wheel. It is directly overhead, up-there, and to the south. It is the house of clear, practical vision (clairvoyance). Ideas can take their start here as planets pass through the 10th house. In the natal chart, the 10th house represents where we have our head above water and can see what to do — clear practical vision. It is therefore associated with career, vocation, and the like. The tenth house holds a clear idea about something — what is often called an out-of-the-body vision or experience, a time when we really get an insight in its totality.
11th House. The 11th house is a movement away from the 10th and down towards the lower hemisphere of the chart. The 11th house takes the clear idea seen in the 10th and resolves to put it to work, to keep it in mind or make it “matter.” We make a commitment to carry the idea into our daily life; that is, carry it across the ascendant (1st house cusp) and into the lower part of the chart, our personal life. The 11th house has to do with plans for action, group goals, cooperation.
