Timelessness
Experientially, eternity is the state we experience when we are
aware of the passage of time, but feel untouched by it. Timelessness,
on the other hand, is the transcendence of time. There is no awareness
of time at all, for there is no differentiation, and hence no
change. Therefore, time is in the midst of now, but eternity is
in the midst of time. (Inner Journey Home, pg 304)

True nature, similarly, transcends time because it is outside
of our time. It contains all time, yet it possesses no temporal
extension, no duration. We cannot look at it within the concept
of time for time is its creation, its product. It is ontologically
prior to time just as it is ontologically prior to space. This
is what we mean when we say true nature is timeless. However,
actually experiencing this timelessness -- knowing one's own mind
and nature from this perspective -- is a far cry from recognizing
it conceptually. It is paradoxical… (Inner Journey Home,
pg 251)

The pure experience of true nature, in its absolute timelessness
and spacelessness, is the experience of the unmanifest. In other
words, true nature in its true and transcendent truth is unmanifest.
The universe, with its space-time, and its underlying spiritual
dimensions, is the manifest. (Inner Journey Home, pg 251)
