Can you gain stream entry by focusing on the links in dependent co-arising http://www.accesstoinsight.org/tipitaka/sn/sn12/sn12.002.than.html.
The buddha says this: "And what is the noble method that is rightly seen and rightly ferreted out by discernment? There is the case where a disciple of the noble ones notices:
When this is, that is. From the arising of this comes the arising of that. When this isn't, that isn't. From the cessation of this comes the cessation of that."
In reference to dependent co-arising, but I wonder whether it's actually a method.
