Relationship by Fate in Chinese / Japanese...

因緣 is the Buddhist concept of a chance meeting or an opportunity that presents itself by fate.

Sometimes this is used to describe a cosmic chain of events or cause and effect.

It also is used to describe predestined relationships between people - and sometimes married couples (although if you want one about marriage, try this: Fate / Destiny of Lovers.

因緣 can also be translated as origin, karma, destiny, affinity, connection, and relation. This all depends on context - seen alone on a wall scroll, this will be read with a “fate/chance” meaning by a Chinese person or a Korean person who can read Hanja.

The more complex definition of this word would be, “Direct causes and indirect conditions, which underlie the actions of all things.”

This concept is known as nidana in the original Sanskrit. Also sometimes presented as hetupratyaya (or “hetu and prataya”), which I believe is Pali.

Note: Japanese will tend to use this version of the second Kanji:
If you order this from the Japanese master calligrapher, expect that you’ll get this version. However, this word often carries a negative connotation in Japanese (bad things happen), as it is used that way in a certain Japanese idiom. Therefore, this may not be the best choice if Japanese is your target language.

緣 represents the fate that brings and bonds people together.

緣 is a complicated single character. It can mean a lot of different things depending on how you read it.

In Japanese, it can mean fate, destiny, a mysterious force that binds two people together, a relationship between two people, bond, link, connection, family ties, affinity, opportunity, or chance (to meet someone and start a relationship). It can also mean “someone to rely on,” relative, reminder, memento, or the female given name, Yori.

It's the same in Chinese, where it's defined as cause, reason, karma, fate, or predestined affinity.

In the Buddhist context, it's Pratyaya. This is the concept of indirect conditions, as opposed to direct causes. It's when something happens (meeting someone) by circumstance or a contributing environment. Instead of a direct cause or act, it is a conditioning cause without direct input or action by the involved people.

Occasionally, this character is used in a facetious way to say hem, seam, or edge of clothing. In this case, it's the seam that brings or holds the clothing together.

Note: Japanese will tend to use the variant of this Kanji shown to the right. If you want this version (and are ordering this from the Japanese master calligrapher), click on the Kanji at the right instead of the button above.

緣分 or Yuan Fen is the fate or chance that brings people together.

This can also mean a predestined affinity or relationship. Basically this is about destiny.
