Headlessness, or finding myself as space & awareness, is always available. As long as there is awareness, I can find myself as space & awareness, as that in which all phenomena arises in the present. It is available in my immediate experience, no matter what else is going on.
Anything else – any particular experiences or insights or skills – come and go. They are here, and then not. They seem to live their own life, and are only occasionally available.
