The Sagittarius/Gemini Axis seems it to be something to work on. They kind of work together and need to be balanced. Mars/Pluto is of course the difficult part, because it's inner transformation. They both can be about warring with your inner thoughts.
There's a lot of educational pursuit there through perhaps gathering information from many cultures, religions, politics, philosophies, and sifting through them finding out what resonates with you. Sagittarius is the truth seeker. The walking library. I'm a Sagittarius Sun with Neptune in Sagittarius, so I can tell you the contradictions usually come from mirroring the collectives contradictions in theories, concepts, belief systems. Gemini kind of likes to compartmentalize, get stuck in duality and polarity at times. This is also learning to rise out of duality and polarity and transcending the good vs. evil, bad vs. good, seeing through a different perspective the conditioning of society and culture.
Sagittarius is fire of course, so you need to be kind of cautious while driving, or doing activities that concern mechanical objects. Sagittarius has away with moving to fast, thinking to fast, and sometimes you have to slow down and relax. Take time to calm your emotions, thoughts, and feelings. Contemplate, observe your thoughts. Keep a journal. I find when I write and dump my thoughts, it keeps my head clear.
Sagittarius/Gemini can both be a know it all, get stubborn with our ideals, and some can get out out of control with their beliefs. This can also be kind of like a wild horse. There's a tendency of not like being controlled, manipulated by others, and having freedom to be your authentic self. There's times you might buck at what people ask you to do out of fear. Afraid to face the shadow side of yourself. Sagittarius rarely likes being trapped. They like to move around and travel in their mind and in the physical. Their adventurers, explorers, and want to discover new things. Gemini is talks about those things, markets, distributes information through many platforms.
In relationships it can be moving to fast and find yourself in the wrong relationships, so you also have to take your time, get to know one another, and slow it down.
Contradiction usually being caught in chaos and confusion. And the more you educate yourself, the more you will liberate your mind and emotions.
