I honestly do not know.
I am sure I would know if I was, but on the other hand, if I really was, I would be way too humble to admit it.
Are there 'degrees of Enlightenment'?
I've had spiritual experiences and some were very beautiful, intense, exquisite...totally indescribable...
Even though I realise they were/are just more of my 'mind playing tricks on me' (I mentally negate all my experiences), I must be careful not to overdo that, or I may miss something important in the process.
I guess I can say I have attained Satori, not full Enlightenment - or maybe I have..
If I have, I can say one thing. Yes, I have lost my ego (only referring to myself as 'I' to be able to speak and relate as a person).
I have totally lost my ego and attachment...the only 'attachment' I have left is that I am totally 'given' to God. I feel the love of God in my heart...
...but as for anything like 'mystical experiences', 'heightened awareness', altered states of consciousness....there has been none of that. None whatsoever.
So, whether that's all a huge bluff, or I am not enlightened yet, I am still trying to figure out.
