En (Buddhism) - En

Japanese: 縁（仏教） - えん

...the phonetic equivalent of inen. In Buddhism, it is believed that there is always a cause for the occurrence and disappearance of all things, and that which is directly related to the occurrence and disappearance is called in, while the indirect conditions that help the cause and produce a result are called en. However, there is no clear standard for distinguishing what is actually a cause and what is en. Inen is interpreted in two ways: "cause and en" and "en as cause," but both are collectively called en, and the occurrence of things due to inen is also called engi (dependent origin), and the resulting result is also called inga (cause and effect).

From [Good Luck]

…A word that expresses truth in Buddhism, specifically called 'en-gi' (cause and effect), or simply 'engi' (dependent origin). It is a unique Buddhist doctrine that sees all phenomenal things, or ui, as arising from two types of causes: hetu (direct cause) and pratyaya (indirect cause). It is said that 'he who sees dependent origination sees the law, or truth, and he who sees the law sees dependent origination.' …

From 【Festival】

...Then the belief developed that if you visit a temple and worship on a day when a particularly miraculous Buddha or Bodhisattva appears, you will surely receive merit. This is called Ennichi, and En means "connection" or "connection" or "cause and effect," and a particular Buddha or Bodhisattva is connected to the prayers of believers so that he or she will be especially miraculous on a particular day. For example, July 10th is called the 46,000 days of Kannon, and it is said that if you visit a temple on this day, the merit will be the same as if you had visited the temple 46,000 times.

From [Matchmaking]

…En refers broadly to human relationships such as parent-child, husband-wife, master-servant, etc., and matchmaking refers to forming such relationships, but generally it refers to forming a relationship between husband and wife or between a man and a woman, and it can also refer to magical customs that form a bond between men and women. Matchmaking is thought to involve a supernatural will, and there are gods and Buddhas in various places that are said to form bonds between men and women, and people pray for good relationships. …

…いんえんの音便。仏教では，すべてのものごとが生起したり，消滅したりするには必ず原因があるとし，生滅に直接関係するものを因と言い，因を助けて結果を生じさせる間接的な条件を縁として区別するが，実際に何が因で何が縁であるかをはっきり分かつ基準があるわけではない。因縁は〈因と縁〉と〈因としての縁〉の二通りに解釈されるが，この両者を一括して縁と呼び，因縁によってものごとの生起することを縁起（えんぎ）とも言い，また，生じた結果を含めて因果（いんが）とも言う。…

【縁起】より

…仏教における真理を表す一つの言葉で，詳しくは〈因縁生起〉といい，略して縁起という。現象的事物すなわち有為（うい）はすべて因hetu(直接原因)と縁pratyaya(間接原因)との2種の原因が働いて生ずるとみる仏教独自の教説であり，〈縁起をみる者は法＝真理をみ，法をみる者は縁起をみる〉といわれる。…

【縁日】より

…そして特別に霊験あらたかな仏菩薩が出現する日に，寺院に詣でて礼拝すれば，かならず功徳を生ずるという信仰が発達した。それが縁日で，縁とは，〈結縁（けちえん）〉または〈有縁（うえん）〉あるいは〈因縁（いんねん）〉のことで，特定の仏菩薩が，特定の日に，特別に霊験あらたかになるように信者の祈願と結びつくのである。たとえば7月10日は観音の四万六千日（しまんろくせんにち）といって，この日に参詣すれば，その功徳は，4万6000回参詣したのと同じになると説かれたりしている。…
