Inasmuch as it was you who asserted that koshi and ground-path are the same, the reason for referencing Mike Sigman is his long-standing use of the term "ground-path" and the effort he's put into making clear what he means by that, both in words and in introductory seminars.
Thus, I was interested in your explanation of the relationship between the two. However, with each question I ask, you move on to another series of assertions which you base on what you feel, simultaneously dismissing the need for any experience (or empirical examination) of the thing with which you have no experience but "feel" to be the same as what you feel you understand.
Sorry to have troubled you.
Oh dear. Is my English not clear enough for you?
I did not assert they were the same. Did I not point out A similarity?
Did I not say that's where it ends?
Did I not explain my interest in what ground path meant and thus explain the differences I found?
Can you read?
I'm not troubled by your enquiry. I give you references to read so that you can see the difference. None of this vaguely equals an assertion of the same.
I don't feel it is the same at all. I'm actually quite happy that it's not.
Maybe you are the one that is troubled by this view.
