The Hartle-Hawking-Vilenkin state is defined on mini-superspace and is semiclassically related to inflationary theory. However, the state suffers a few problems connected to the path integral of Euclidean or the Lorentzian measure of metrics. In this talk, we will explore a way around these issues by working in the (Ashtekar) connection representation, a real Kodama-Chern-Simons state. We find a generalized "Fourier Transform" that related the Chern-Simons-Kodama state to the Hartle-Hawking state beyond mini-superspace. We end with some discussion and open ended questions for cosmology and quantum gravity.
