Hello Dipo,
I had made an error in that statement you quoted.
It should read, “When one gets rid of all ten micchā diṭṭhi, one is truly on the Noble Eightfold Path.” I just revised the post. It is #9 of the post, “Micchā Diṭṭhi, Gandhabba, and Sōtapanna Stage”
– Just to emphasize: One who has removed the 10 types of miccha ditthi is only on the mundane path UNTIL grasping Tilakkhana. One is on the Noble Eightfold Path when one has removed the 10 types of miccha ditthi AND understood Tilakkhana.
(By the way, please provide the link to the post in question (that you quote). Otherwise, I have to spend time searching for the post)
Yes. It is easier for someone who does not have the 10 types of miccha ditthi to grasp the Tilakkhana.
