I Ching essentials
Mutual Maps
Describes the weather between you.
A mutual map is a reading of the relationship itself. It is built from two birth triads, computed once, and named through a small set of recurring patterns the I Ching has used to describe how two people meet. Same two birth dates, same map, every time.
Each map carries five lenses on the relationship and one tier name for its overall shape. The lenses describe the weather from five angles: what charges across the gap, what already harmonizes, what surfaces in each other, where the friction sharpens, and what the book counsels for the pair. None of it is a verdict on either person. The relationship is the third thing, with its own shape.
The Five Lenses
A mutual map reads the same two birth triads through five different lenses. Each lens asks a different question of the same pair. Together they describe the weather of the relationship, not a verdict on either person. The relationship is treated as a third thing, with its own shape.

The Creative
Hexagram 2
The Receptive
Spark
the charge between you
Heaven and Earth, met under the Spark lens. The most polar pair in the book stands across a charged gap. The reading is not about who is right or who leads. It names what passes between two opposite shapes the moment they share a room.
Spark reads the boundary the moment two patterns meet. Not chemistry as a marketing word, but the actual charge that crosses the gap and where it first lands. Some pairs spark on initiative, some on attention, some on stillness. The lens names what is alive between you before either of you decides what to do with it.
Hexagram 11
Peace
Hexagram 42
Increase
Resonance
what naturally harmonizes
Peace and Increase, read through Resonance. Two patterns that already breathe at compatible frequencies. The lens listens for the lines that ring true on both sides without needing translation, and tells you where the relationship rests easily.
Resonance reads the lines that already ring at the same frequency on both sides. These are the places where your inner patterns continue across the gap without needing translation. Resonance is not always loud. Often it is the quiet agreement underneath disagreement, the part of you that is already understood.
Hexagram 29
The Abysmal
Hexagram 30
The Clinging
Shadow
what you reveal in each other
The Abysmal and the Clinging, read through Shadow. Water that hides its depths against fire that gives off its light. Each pattern reveals what the other tends to keep covered, and together they expose what neither could show alone.
Shadow reads the aspect of yourself that only becomes visible when this particular person stands beside you. The relationship acts as a mirror, sometimes flattering, often not, always useful. The lens is not about blame. It is about which parts of you the other person makes legible, including parts you tend to hide from yourself.
Hexagram 49
Revolution
Hexagram 50
The Cauldron
Edge
where you grow through friction
Revolution and the Cauldron, read through Edge. Two transforming patterns pressed against each other. The lens names the productive friction: the place where honest collision sharpens both of you, rather than wounding either.
Edge reads the productive friction. Not every difference is a wound. Some are whetstones. The lens names the place where honest collision sharpens both of you, where your patterns refuse to dissolve into each other and so each one stays clear. Useful friction has direction; this lens shows you which way it points.
Hexagram 50
The Cauldron
Hexagram 32
Duration
Oracle's Counsel
the book speaking into the room
The Cauldron and Duration, read through Oracle's Counsel. Transformation listening to continuity. The book speaks into a pairing where one vessel asks for change and one pattern asks for holding, and it counsels the relationship on how to keep both at once.
Oracle's Counsel reads the I Ching speaking into the relationship itself. A third hexagram is cast for the pair, not for either of you alone. It carries the book's voice into the room you share and offers a posture rather than a prediction. The advice belongs to the relationship, not to either party.
The lenses are easier to read once one of them is yours.
Bond Level
Bond Level names the overall shape of the connection in four layers: how the hexagrams meet, how the birth triads interlock, how the five elements move between you, and how the sexagenary cycles align. Each layer reads the relationship from a different altitude. The four readings combine into a single tier name. The tier is qualitative, not a score, and it points at texture rather than rank.
Spirit Bond
An effortless meeting of inner weather. The friendship recognizes itself on arrival and asks little of either person to maintain.
Sacred Bond
Deep and rare. The connection holds steady through long absences and returns to the same temperature whenever you meet again.
Harmony Bond
Companionable and warm. The patterns fit comfortably side by side, with enough overlap to share a rhythm and enough difference to stay interesting.
Growth Bond
A friendship that changes both of you. The fit is partial on purpose. What is unfinished in each pattern gets worked on through the other.
Challenge Bond
A friendship with real edges. Genuine affection runs alongside genuine differences. Care and honesty together make the connection workable.
Tempering Bond
Unconventional and intense. The friendship asks more attention than most and rewards it with a kind of sharpening neither pattern could do alone.
Both readings are descriptive, not punitive. A lower tier names a shape that asks more attention; it never reads as a worse person or a failed pairing.
Methodology
Around ten thousand pairs were validated against a rigorous editorial rubric before launch. Each mutual map is generated once and cached permanently. The same two birth dates always read the same way, in any language we support. Nothing is recalculated behind your back.
