Interdependent is Mutual - 2 ways. 2 object have to be there to interact.
Dependent origination is 1 way. Only 1 object has to be there. The previous object already cease.
I found this to be immensely clarifying, thank you.
You are making a mistake though, depedent origination is not linear but cyclic. Ignorance is the cause of mind and matter but mind and matter is also the cause of ignorance.
I've always suspected this.. well, not always
, but ever since I started studying Buddhism - though I don't think any dharma book I have read ever said it that explicitely. I think this interdependence issue all ties into the five skandhas:
The first skandha (sankhara or thought formations) arise from ignorance (avijja). Matter (rupa) & consciousness (vinnana) are mutually dependent on one another: consciousness must be conscious of something
, like form or thought, but form is a meaningless abstraction unless someone is conscious of it. Where there is consciousness of form, perception (sanna) is born. Where there is perception, feelings (vedana) arise. Pleasurable feeligns cause craving (bhava-tanha), painful feelings cause repulsion (vi-bhava-tanha). Any kind of tanha leads to grasping and attachment, which leads birth, death, and rebirth ad infinitum.
Ignorance causes thought formations (sankhara)
thought formations and form (rupa) must be perceived (sanna) to exist.
There must be a consciousness (vinnana) to do the percieving (sanna).
There must be sensation (vedana) to provoke consciousness (vinnana).
There must be matter/thought (rupa,sankhara) to provoke a sensation(vedana) .
Ignorance-->Thought Formations/Matter-->Perception-->Consciousness-->Sensation-->Thought Formations/Matter-->Ignorance
You take out any one of these aggregates and the whole cycle collapses.
