Some parts of your natal chart are more important than others, and one big part is the angles. But not all angles are made equal to everyone's natal chart, and one likely stands above the others as being more important in your own life. Which one is it for you?
What are the Angles in astrology?
The angles in astrology refer to the Ascendant, Imum Coeli, Descendant, and Midheaven. They rule the 4 main pillars of your life - the self (Ascendant), the home/family (Imum Coeli), others/relationships (Descendant), and goals/direction (Midheaven).
They usually link to the angular houses (depending on the house system you use). But we all tend to give more attention to one or two of these parts of our lives than the others.
Which angle is most important for you?
The most obvious will be when one of your natal planets is conjunct (aligned with) an angle. That almost always elevates it significantly and makes that angle your most important.
The planet conjunct it can be super important for the angle itself as well (sometimes even more than the sign it's in). The planet ends up being dominating energy and really takes over whatever the angle rules.
If you have multiple planets in one of the houses that link to an angle, that can make the angle most important for you. The Ascendant links to the 1st house, the Imum Coeli links to the 4th house, the Descendant links to the 7th house, and the Midheaven links to the 10th house. This is most evident when you have a stellium (3+ planets together in one Zodiac sign) in one of these houses, but can also be the case with just the Sun or Moon in one of these houses.
Another option can be if the planetary ruler of the angle is elevated in your natal chart. The ruler is the natural planetary ruler of the sign the angle is in. If the ruler is anaretic, part of a stellium, your most or least aspected planet, a singleton - this can elevate the ruler and thereby elevate that angle for you.
You may find you have more than one angle that is elevated, and you may find your whole life revolves around those two or three areas. You may have a highly active life, constant activity and busy-ness, but may struggle at times with the slow and quiet parts of life.
The most important angles:
When your Ascendant is more important in your natal chart, you may give a lot of extra attention to you as a person, what you want for yourself, how you present yourself, and your identity. You can have a strong personality, depending on the planets involved, and may feel more comfortable alone than with others, and need to work on balancing your needs and the needs of others.
When your Imum Coeli is more important in your natal chart, you may give extra attention to matters of the home and family. Your home and family life can be more important to you feeling solid and secure as a person. Your early life is likely super influential on you, for better or worse (depending on the planets involved). You may care more about the internal than the external, and may need to work on balancing that.
When your Descendant is more important in your natal chart, you may give extra attention to your relationships and the people in your life. You may be super helpful, and want to do whatever you can for those you care about. You may feel more comfortable with others than alone, and balancing that with your own needs can be important.
When your Midheaven is more important in your natal chart, you may give extra attention to your goals and direction. You can be highly ambitious, and set big goals for yourself in your life. You can achieve a lot, take on many responsibilities, and may achieve status. You may care more about the external, and need to balance that with the internal.
