The doctrine of pratītyasamutpāda, (Sanskrit; Pali: paticcasamuppāda; Tibetan Wylie: rten cing 'brel bar 'byung ba; Chinese: 緣起) is an important part of Buddhist metaphysics. It states that phenomena arise together in a mutually interdependent web of cause and effect. It is variously rendered into English as "dependent origination", "conditioned genesis", "dependent relationship", "dependent co-arising", "interdependent arising", or "contingency".
