Some traditions like to differentiate between awakening and enlightenment. In my opinion awakening really begins with insight that self is ephemeral and appears on a vastness of inner space… in the way that the reality map on this website, along with these letters, appear on a background space.
This space is consciousness.
This is what you really are, prior to the comings and goings of your personality. Over time this is deeply integrated into your body, and with mastery of your seeing, the dominion of your parts and their hold as your identity are broken down. This is when awakening becomes mature, and this I would call enlightenment.
