What's the Difference Between a Clash and a Combination?

A combination (合) is a relationship where characters pull toward each other and bind together; a clash (沖) is a relationship where opposing currents of energy meet head-on. Neither is a ruling on good or bad fortune — both are simply clues to where energy is gathering and how it's moving. Not a fixed fate, just a reference.

Combination — is binding always good?

When a combination forms, the energy of the two characters can blend and even transform into a new Element. It's closer to two people whose temperaments click and who end up working as a team. But because the characters are bound together, each can also pause its usual role for a while — so a combination isn't automatically good. The types range from the stem combinations and Six Combinations up to the Three Harmony combinations, where three branches gather into one larger Elemental current.

Clash — is colliding always bad?

The clashes among the Earthly Branches form six pairs — Rat–Horse, Ox–Goat, Tiger–Monkey, Rabbit–Rooster, Dragon–Dog, Snake–Pig — so they're also called the Six Clashes. When a clash forms, the energy of the characters gets shaken up, and change or movement tends to follow. Tradition sometimes read this as an unsettling signal, but it can also be the very stimulus that gets something stuck moving again — reading it as "a trigger for change" rather than "a breakage" is the more balanced view.

The relationships between characters don't stop there — there's also the Ten Gods, the relationships read from the Day Master. Both are part of the grammar written across the stems and branches that make up Iljin and your Day Pillar.
