user17586: For the longest time, I never had much to question about it but I've taken to wondering about an extra one, one that wasn't there before. I get to feeling that "right spirit" should be another fold. Can Buddha's spirit be tested for this?

user295: There is the:

8 Fold Path is the practice up to Sotapanna, and
10 Fold Path for full enlightenment

The Noble 8 Fold Path is the practice up to Sotapanna.

To go beyond Sotapanna one must add 2 more elements under liberation/release which are:

right knowledge
right freedom
