"We talk about the 2nd line as an archetype in the context of the hermit.
Unfortunately that name in many, many ways is misleading, though it's very true, but it's misleading.
That is, the assumption is that the 2nd line is always closed off.
And the thing to recognize about the 2nd line is that it's waiting for the call, which means that it can never be completely closed off, which means that it's open to something.
...
If you go down to the tonal level what you get is this ability to be able to be ready for the unknowable. You'll know it when you see it, but you don't know what the hell it is until you see it.
You know it when you see it, when you hear it, or smell it, or taste it, or whatever the case may be.
But the reality is that it is a capacity to be protected, in a way, more than just closed off."
