“Pratityasamutpada”, a Sanskrit work often translated as “dependent origination”, is a way talking about that which appears in terms of cause and effect. “The Twelve Nidanas”, the twelve links on the chain of existence, is a conceptual model used to look closely how one apparent situation conditions the next. It is a way of working with suffering in strengthening awareness of fixation.
The ultimate situation, expressed in a relative way, is “not two”. Everything is dependently arisen.
