Chart rulers (in the houses)
The chart ruler of a natal chart, is the planet that is ruled by the ascendant. Since the ascendant is also associated with the soul’s purpose, the chart ruler is a very important planet, since it takes action for the ascendant and therefore rules the chart. So, where your chart ruler falls is quite important, and the same for aspects to it.
The chart ruler(s) for every ascendant:
Aries asc —> mars
Taurus asc —> venus
Gemini asc —> mercury
Cancer asc —> moon
Leo asc —> sun
Virgo asc —> mercury
Libra asc —> venus
Scorpio asc —> pluto (traditionally mars)
Sagittarius asc —> jupiter
Capricorn asc —> saturn
Aquarius asc —> uranus (traditionally saturn)
Pisces asc —> neptune (traditionally jupiter)
(for me personally, i tend to relate to traditional planets more, so definitely check that out too if your rising sign also happens to have a traditional ruler)
Chart ruler in….:
(for aspects with your chart ruler, look for conjunction first, since those have the most influence)
1st house/aries/aspect with mars: Your faith is in your own hands, and you are the person that can makes changes to your own life, you’re the leader. You’re quick and active in the way you approach life. You’re aware of yourself, but maybe a little too much sometimes. Try to not always be the fastest, taking things slow is okay too.
2nd house/taurus/aspect with venus: You value stability, comfort and security in life. You’re focused on your purpose and want to get there the ‘right way’, but remember that all ways are the right one, since it’s your life, mistakes happen. You might not always be motivated, but don’t let that influence your self image.
3rd house/gemini/aspect with mercury: Curiosity, knowledge and restlessness describe your soul’s purpose pretty good. You approach life quite active, but also very observing. Don’t forget to stay true to yourself in conversations, since your views on life can be quite versatile and easily influenced by others.
4th house/cancer/aspect with moon: This is a great indicator for a true homebody, even when your chart ruler is an active planet like mars. You like to build a safe place for yourself everywhere you go. You might also value animal lives a lot, or just other living things in general. With your chart ruler here, you are a very giving person, but don’t forgot yourself!
5th house/leo/aspect with sun: Your energy mainly goes to your hobbies, since this placement makes you very creative. You like expressing yourself and it motivates you to achieve your goals. You might also like to be pointed out or get complimented, but make sure you don’t rely on it, you are also good enough without that reassurance.
6th house/virgo/aspect with mercury: Your job and life goals can be on your mind quite a lot. Physical activities stimulate you, just like food/diets, since you can be quite body-aware and it helps you build confidence. You are a very helpful person and will do everything to help others, but please don’t forget yourself, you matter too.
7th house/libra/aspect with venus: Any kind of relationship and bonding with other people is very important for you. You can have a hard time figuring out what your goals and purpose are and might rely on others to figure it out. Build some confidence in the unknown to be more independent.
8th house/scorpio/aspect with pluto(/mars): You tend to always read the room, you can be private and sometimes even mysterious. The psychology of life really appeals to you, since you can feel very misunderstood yourself. You are self-aware, which you use to change and sometimes even transform yourself. You are likely to be drawn to the unknown.
9th house/sagittarius/aspects with jupiter: You like to have freedom and to teach and learn. You’re outgoing and a dreamer who is willing to travel and make new experiences, good and bad, to get to your goal. Since you’re an idealist, don’t overestimate your goals, because that might leave some self-consciousness in your abilities.
10th house/capricorn/aspects with saturn: You have strong desires and goals in life and feel like your reputation and the things you’ve accomplished are important. You like recognition for your work and tend to come over as professional. This all makes you a strong person, but don’t forget that it’s good to be soft too at certain points of life.
11th house/aquarius/aspects with uranus/saturn: You like to have people around you with the same vibes and these bonds are important for you. Equality and freedom is also something you want to achieve throughout your life. You’re quite social and outgoing, but in the end, you prefer deep bonds.
12th house/pisces/aspects with neptune/jupiter: your approach on life can be shy, intuitive and sensitive, which makes it hard and overwhelming to be around people sometimes. You’re always seeking for a higher something and meaning of others. That can make you anxious and lonely, because not everybody gets you. Try to remember that eventually you will find your place in the universe, but it takes time.
