Many people has the notion that enlightenment is one state. Many also believe that when it is attained, a person is forever in that state. The following is not a definitive article on this subject. It is just an expression of my own thoughts.
My opinion is that enlightenment is not just one state but is a progressive and gradual establishing of states of consciousness. I, myself have not reach the end of the road. But from years on a spiritual quest, I can safely say that enlightenment happens in a series or stages of self-realisations and self-discoveries.
Usually there is a di erence between an initial awakening and a later stabilisation of that stage that happens through practice or experiences. The initial awakenings are new discoveries about the dynamics of consciousness, while the stabilisation is the assimilation of what is being discovered into one’s life experience. Sometimes, a new discovery can completely over-rule or modify upon an older one.
