Fire
Agni
Spirit, initiative, will. Burns to create.
Compatibility
How two signs meet.
Compatibility is not a verdict — it is a vocabulary. We read two axes: element (Fire / Earth / Air / Water — the energy) and modality (Cardinal / Fixed / Mutable — the posture). Pick your sign and theirs.
Water · Cardinal · Cancer
Fire · Cardinal · Aries
Cancer × Aries
Water meets Fire
Element — the energy
Steam — Fire boils Water, Water tempers Fire. Volatile, but creative.
Cardinal meets Cardinal
Modality — the posture
Two starters — both want to lead. Brilliant for launching shared projects, brutal at deciding whose plan wins. Take turns or build parallel kingdoms.
✦ Element pairs describe texture; modality pairs describe posture. Both shape how two people meet — neither decides destiny. Every pairing can work; every pairing has its own work to do. Birth chart synastry (planet-by-planet comparison) ships with our paid compatibility report.
Tarot lens
Your cards in the deck
Every sun sign has one Major Arcana correspondence in the Golden Dawn system. Read the two cards together as a portrait of the dynamic.
The four elements
Every sign belongs to one of four elements.
Compatibility begins here — how do these two elements meet?
Earth
Prithvi
Body, form, persistence. Builds to last.
Air
Vayu
Mind, language, exchange. Connects to know.
Water
Jal
Feeling, depth, memory. Holds to heal.
The three modalities
Every sign also has a posture.
Element is the energy; modality is the posture — whether the sign initiates, sustains, or adapts. Two people can share an element but read each other very differently if their modalities clash.
Cardinal
Initiators
Start the season — launch projects, set direction, push first.
Fixed
Sustainers
Hold the season — commit, persist, refuse to drift. The keepers.
Mutable
Adapters
End the season — translate, dissolve, prepare what comes next.

◇ The other matrix
Nine possible postures
Three modalities × three modalities = nine pairings. How initiators, sustainers, and adapters meet.
Cardinal × Cardinal
Aries·Aries →
Two starters — both want to lead. Brilliant for launching shared projects, brutal at deciding whose plan wins. Take turns or build parallel kingdoms.
Cardinal × Fixed
Aries·Taurus →
Engine and anchor — you start, they hold. The most productive pairing if you respect their pace. Frustrating if you mistake their steadiness for stubbornness.
Cardinal × Mutable
Aries·Gemini →
Push and flow — you set direction, they shape-shift to fit. Easy and generative, until you wonder if they have an opinion. Ask them. They do.
Fixed × Cardinal
Taurus·Aries →
Anchor and engine — they start, you hold. You build what they begin. Resentment can creep in if they keep launching and never finish; speak up early.
Fixed × Fixed
Taurus·Taurus →
Two anchors — committed, loyal, immovable. The deepest bonds and the bitterest standoffs live here. When you disagree, neither bends. Choose your battles.
Fixed × Mutable
Taurus·Gemini →
Pillar and tide — you stand, they flow around you. Soothing for both, but watch for hidden resentment: they may feel unseen, you may feel evaded. Name it.
Mutable × Cardinal
Gemini·Aries →
Flow and push — they set direction, you adapt and translate. You make their visions actually work in the world. Don't lose your own thread in their wake.
Mutable × Fixed
Gemini·Taurus →
Tide and pillar — they stand, you flow. You feel them; they may not feel you. Ask for the explicit acknowledgement you need. They can give it once asked.
Mutable × Mutable
Gemini·Gemini →
Two adapters — endless flexibility, infinite negotiation, occasional drift. Beautiful conversations, fewer landed decisions. Pick one anchor between you.
