Thank you for your take on this, Frank. Maybe all the different definitions of enlightenment are all valid experiences that happens to be labelled with the same word. Maybe it's like varieties of an apple, or breeds of a dog. Someone who has seen all breeds of dog might say to someone who has only seen a chiwawa, "You've only seen a chiwawa, so you don't fully understand what a dog is". But the chiwawa is still 100% dog.
