I am sorry I must have misunderstood, you used the phrase "direct perception" as if it was something different from perception.
I don't really understand your example of the "gut" in relation to internal & external. How does recollection of the gut back up "traditionalist views" on internal & external.
Rather than read Ven Analayo's extended discussion I think you should read http://www.accesstoinsight.org/tipitaka ... .than.html
If you were to read this sutta and MN 62 you would have the actual teachings.
As it is I will look up the reference you have given.
