Every mount you have studied so far occupies one location — one elevation, one zone, one place to press. Mars is different. Before you look at your hand, register this: Mars is the only classical mount with two distinct and separate positions on the palm. There is no single elevation to find. There are three regions to locate — two active zones and the connective territory between them — and they carry meaningfully different associations from one another.
The names shift depending on which source you are reading. Some texts use Inner Mars and Outer Mars; others use Mars Positive and Mars Negative, or Active Mars and Passive Mars. This lesson uses Lower Mars and Upper Mars, which corresponds to how the zones appear in most classical Western diagrams. The Plain of Mars lies between them — the central palm, often slightly hollowed, connecting the two zones without being reducible to either.
Finding the three zones
Hold your hand palm-up, fingers pointing away from you.
Lower Mars occupies the narrow strip on the thumb side of the palm — the radial side. Its territory runs from just below the Mount of Jupiter at the index finger’s base, downward along the inner edge of the life line toward the wrist. The life line itself forms its outer boundary. The zone is narrow: a strip of tissue between the line and the thumb’s base, not a broad padded elevation like Venus or Luna. Place your opposite fingertip against the inner edge of your life line, at mid-height on the palm. That strip of tissue between your fingertip and the thumb’s inner margin is Lower Mars territory.
Upper Mars occupies the percussion edge of the palm at mid-height — the outer edge, on the little-finger side, in the zone between the heart line above and the upper boundary of the Mount of Luna below. To locate it, place your opposite fingertip at the outer edge of your palm, approximately halfway between the base of your little finger and your wrist. Press gently inward. Unlike the broad, sometimes soft elevation of Luna below, Upper Mars tends to feel denser and more resistant when developed — a distinct firmness at the mid-height outer edge.
The Plain of Mars is the central palm between them: the flat or slightly hollowed zone you cross when you draw your fingertip from one side of the palm to the other at mid-height. Cup your hand gently; the hollow that forms in the centre is the Plain. It is not elevated like a mount — it is the connective terrain between the two Mars zones.
Lower Mars: the courage to act
Lower Mars is traditionally associated with what Cheiro called “the fighting force that enables the individual to assert himself and push through obstacles” (Palmistry for All, 1916). Benham, in The Laws of Scientific Hand Reading (1900), characterised the zone as governing “aggressiveness, combativeness, and physical courage — the capacity to attack rather than defend, to initiate rather than resist.” Gettings, in The Book of the Hand (1965), described its essential quality as “the martial impulse in its outward form: the desire to enter, engage, and overcome through action.”
The term the tradition reaches for consistently across these sources is active courage: the energy that starts things, enters friction rather than withdrawing from it, and presses forward through difficulty it can act upon. This is not the same as aggression — the classical sources are explicit about that distinction. A well-developed Lower Mars carries initiative, physical vitality, and directness; aggression is associated specifically with overdevelopment, not with the zone at proportionate expression.
Now press the strip of palm just inside your life line on the thumb side, at mid-height. Does it feel distinct from the surrounding palm — slightly firmer, slightly more present? Or does it feel continuous with the flat inner palm, undifferentiated? A flat Lower Mars zone — no distinct elevation or firmness — is traditionally associated with reduced physical initiative, reluctance to engage with confrontational or demanding situations, and less of the vital forward energy that characterises the zone when it is active.
Upper Mars: the courage to endure
Upper Mars carries what Benham described as “the quality of moral courage, resistance, and the capacity to bear pressure, opposition, or difficulty without yielding.” Where Lower Mars acts, Upper Mars holds. Where Lower Mars presses forward into a situation it can engage directly, Upper Mars does not yield to a situation it cannot immediately resolve through action.
The distinction is significant enough that the tradition treats this as a different category of courage. Gettings described Upper Mars as governing “persistence in difficulty and the resistance to opposition that can, in its positive form, be the basis of great moral strength.” West, in The Complete Illustrated Guide to Palmistry (1998), emphasised that this endurance extends into the emotional register: the capacity to absorb sustained social or emotional pressure without disintegrating.
What the tradition is naming here is not the dramatic moment but the long unglamorous work of not breaking — the person who holds their position without requiring the situation to resolve quickly, who sustains under pressure without performing that they are sustaining. This is courage without the action that announces itself.
Press your Upper Mars zone again at the outer mid-palm edge. A firm, distinct elevation at the percussion edge at this height is traditionally associated with this enduring quality. A flat or absent development is traditionally associated with difficulty holding positions under prolonged pressure — susceptibility to discouragement when opposition extends over time rather than resolving, and a reduced capacity for the quiet, persistent resistance that this zone at full expression represents.
The Plain of Mars: the ground between
The Plain of Mars is not empty space. Benham treated it as part of the Mars complex, not as neutral territory between two active zones, and the quality of the central palm is part of the reading.
A Plain that is firm, well-proportioned, and moderately filled is traditionally associated with a balanced relationship between active and enduring energy: neither impulsive action nor passive resistance dominates, and the two forces check and support one another across the central ground. A markedly hollow centre may suggest that Lower and Upper Mars operate as relatively independent qualities — present, but without the integrating ground that makes them a coherent whole rather than a summary of two separate tendencies.
Cup your hand gently now and look at the central palm. On some hands the hollow is deep; on others it is barely present, the palm filling quite evenly. Neither extreme is disqualifying — the reading is about relative proportion and the relationship between the centre and the two zones flanking it.
How development reads across all three zones
A developed, firm Lower Mars alongside a flat Upper Mars may describe someone whose energy is active and initiating — who enters situations readily — but whose capacity for prolonged, sustained endurance under opposition is more limited. The reverse — flat Lower Mars, developed Upper Mars — may describe someone whose courage is moral and persistent rather than physically assertive: not first into the room, but last to yield. Neither configuration is a flaw; each describes a different distribution of the same energy across two forms.
Overdevelopment shifts both zones toward shadow. An overdeveloped Lower Mars — significantly more prominent than the surrounding palm, particularly when hard and dense — is associated in the classical sources with combativeness, short temper, and a reflexive aggression rather than considered assertion. Benham was precise: overdevelopment here often accompanies “a quarrelsome disposition, rashness in action, and a difficulty in distinguishing between assertion and aggression.” An overdeveloped Upper Mars — the resistant firmness pushed to excess — is associated with stubbornness and inflexibility: the holding force that will not release even when change is warranted, endurance that has become immovability. Benham and Gettings both note that an overdeveloped Upper Mars can produce a persistent, passive resistance to all external influence — firmness calcified into refusal.
As with every mount, overdevelopment is not simply prominence. It is prominence that stands out of proportion relative to the hand as a whole — a quality that unbalances, not merely one that is clearly present.
What other traditions say
Hasta Samudrika Shastra, the Indian classical system, names the Mars zones Mangal Parvat — the Mount of Mars, from Mangal, the planetary intelligence governing Mars in Jyotisha. The tradition distinguishes between Uttam (upper/positive) and Adham (lower/negative) Mangal Parvat, corresponding broadly to Upper and Lower Mars in the Western system. Mangal governs vital force, drive, martial energy, and the capacity for both physical and moral courage — consistent with the Western reading.
The Indian framing adds a specific texture through the concept of shakti — vital force — that expresses differently depending on its zone. Positive Mangal channels this force outward through action and assertion; negative Mangal holds it inward through resistance and endurance. The same underlying energy directed differently by position — a framing that reinforces the Western structural distinction rather than diverging from it.
Chinese palmistry organises the palm through a different conceptual framework, and no direct equivalent to the Mars mount structure can be named here without misrepresenting how that tradition works. Where Chinese palmistry addresses energy, drive, and resistance, it does so through its own structural logic. The two traditions are neighbours in their concerns here without being equivalents in their method.
Lesson takeaway: Mars is unique among the classical mounts in occupying two distinct zones on the palm, connected by a third region between them. Lower Mars — the narrow strip on the thumb-side inner edge inside the life line — is traditionally associated with active courage: the energy that initiates, presses forward, and engages directly with difficulty rather than circumventing it. Upper Mars — the firm zone at the percussion edge at mid-height, between the heart line and Luna — is traditionally associated with enduring courage: the energy that holds position, resists sustained pressure, and does not yield to what cannot be immediately overcome. The Plain of Mars, the central palm between them, is a connective moderating ground, not neutral space. Assess each zone independently for elevation and firmness relative to the surrounding palm, then read them together: the balance, asymmetry, or overdevelopment of one zone relative to the other is part of what the hand is showing you. Neither active courage nor enduring courage is preferable in the abstract — the palm describes how these two forms are distributed in a given character, with each carrying its positive expression and its shadow when pushed to excess.
