When you continuously know and sense yourself as the space of consciousness rather than what appears in consciousness - sense perceptions, thoughts, emotions - then it can be said that you are enlightened... except that you wouldn't think or speak of yourself as 'enlightened', because that would instantly create another mind-based conceptual identity and so it would be the end of 'your' enlightenment.
Eckhart TolleSpace has no "existence." "To exist" literally means "to stand out." You cannot understand space because it doesn't stand out. Although in itself it has no existence, it enables everything else to exist. Silence has no existence either, nor does the unmanifested.
Eckhart TolleSurrender is surrender to this moment, not to a story through which you interpret this moment and then try to resign yourself to it.
