Mars square Jupiter creates tension between action and scale, will and conviction, struggle and the right to consider oneself right. Mars wants to attack, begin, win, and defend desire. Jupiter wants meaning, justice, influence, recognition, ideology, and expansion. In the square, the person may have great strength and knowledge, but spend them in the wrong direction: arguments, excessive risk, exaggeration, and battles for personal rightness.
The aspect often gives interest in politics, morality, law, religion, social questions, sport, and business. The person is not indifferent to injustice and is irritated by lies or weak principles. But Mars quickly sets Jupiter on fire: where argument is needed, anger appears; where a plan is needed, a rush appears; where wisdom is needed, the person proves they are right at any cost.
