Riemannian
Reality is composed of many dimensions, all necessary for manifest
forms and our experience of them. It also reveals their hierarchic
functioning, which in turn points to the absolute as the apex
or center of that hierarchy. It reveals the objective relation
of the absolute to manifest reality as the center of a hierarchy
of manifestation, and shows us that by descending into manifestation
the absolute descends into an increasing number of dimensions.
It also shows that this hierarchy of manifestation is not temporal
or spatial, but ontological. The integrated dimension reveals
the manifest world as a Riemannian multidimensional manifold,
and shows the hierarchical relationships of the functioning of
its various dimensions. (Inner Journey Home, pg 433)

Riemannian Manifold
Viewing our consciousness in terms of its dimensions, we see
that it is not a three-or four-dimensional field, but a multidimensional
manifold, a manifold in the sense that it is a dynamic structure
of dynamic structures. This manifold is characterized by a nonlinear
-- Riemannian -- geometry, in that all the dimensions open up
to all the others in nonlinear ways. Even in ordinary human experience,
we can be aware of many different levels of experience in a given
moment... All our inner experiences are manifestations of forms
within the manifold of our consciousness, where these forms are
nothing but the very fabric of this consciousness morphing itself
at particular regions. This view is not only a more faithful rendering
of our inner experience, but clearly reveals the purpose of inner
work. This purpose is realizing the awareness of the field of
consciousness itself, which makes it possible for us to inhabit
our inner field completely in all of its richness and freedom.
