How does ‘Knowledge and Vision’ of Dependent Origination come about, in relation to the third and fourth Noble Truth?
Bit by bit, depending how much one doesn’t grasp and keeps letting go, the fetters are removed.
Little by little, Right View is established, until finally, the defilements cease, which is the Third Noble Truth.
Then, Right View and the Eightfold Path become the automatic way of functioning. This is called the Fourth Noble Truth.
