Mars and Jupiter in Aspect

Mars acts and Jupiter enlarges. Together they produce someone who attempts things at a scale other people find alarming, succeeds more often than the odds suggest, and consistently underestimates what the attempt is going to take.

The technical picture

Mars: personal, classically malefic
Jupiter: social, classically benefic
Angles possible: Conjunction 0 degrees, Sextile 60 degrees, Square 90 degrees, Trine 120 degrees, Opposition 180 degrees

The core tension

This is the enterprising combination. Energy is abundant, confidence arrives before evidence, and the instinct in almost any situation is to go bigger. A great deal gets built this way, because most opportunities are only available to whoever is willing to walk toward them and this contact always is. The weakness is arithmetic. Nothing in the pairing supplies a sense of proportion, so effort gets committed on enthusiasm and the bill arrives later. Physical energy is usually high and wants spending, and the same appetite that drives the work turns up in everything else a person does.

Conjunction (0 degrees, same degree)

Force and scale run together. People with this contact start things, and they start large. Courage is genuine and mostly unexamined, since it has usually been rewarded often enough to seem like realism. Physical vitality tends to be strong; sport, travel and hard work all suit it, and a life without exertion goes sour quickly. Enthusiasm is contagious enough that other people get recruited into plans they would not have made themselves. The difficulty is that a project is committed to before it has been costed, and the person doing the committing genuinely believes the estimate at the time.

Sextile (60 degrees, a sixth of the circle)

The drive is available at whatever size the situation wants. A person with this contact can go large when it is worth it and stay proportionate the rest of the time, which is the most usable version of this pairing. Opportunity tends to arrive through doing and not through waiting. Nothing forces it, so a real capacity for the ambitious attempt can go unspent on a comfortable life.

Square (90 degrees, a quarter of the circle)

Energy and scale argue. The recurring shape is overcommitment followed by a scramble, then a period of caution, then another overcommitment. Effort gets spent generously in the wrong direction and there is often real frustration at how much work produced how little. Risk-taking is more literal here than at the other angles, financially and sometimes physically. What develops over a couple of decades is judgement about scope, which is the specific thing the trine never learns, and which converts a person from someone who attempts a great deal into someone who finishes it.

Trine (120 degrees, a third of the circle)

Action and expansion agree. A person with this contact works hard without it costing much, aims high without much anxiety, and tends to be lucky in a way that is difficult to separate from being willing. It works. The catch is that a confidence never contradicted does not know its own error rate, and this contact can carry someone a long way past the point where a second opinion would have helped.

Opposition (180 degrees, half the circle)

The scale gets met in someone else. Rivals, partners and institutions that are larger, better resourced, or simply more certain, and a pattern of matching their size at your own expense. Competition is a recurring theme and frequently productive. There is often a stretch of taking on more than is sustainable in order to hold a position against somebody. It settles when a person works out their own measure and stops calibrating against whoever is opposite.

Working with it

Cost the thing before agreeing to it, in hours and money, written down. This combination is reliable about what is possible and unreliable about what it takes, and the gap is where the trouble lives. Spend the physical energy deliberately and early. Find one person who will tell you the plan is too big, and listen properly rather than politely. And keep the willingness to attempt things, since most of what this contact has built came from being the one who moved.

Questions to sit with

What did you commit to before working out what it would cost?
Which effort produced far less than the energy you put in?
Who is allowed to tell you the plan is too big?
