Ching Ch'ing, a Chinese Ch'an master, asked a monk:
-What is the sound outside?
The monk answered:
-That is the sound of rain.
The master said:
-Sentient beings are upside down, they lose themselves in pursuit of things.
I recently started a new job. It is very repetitive and doesn't require any thoughts. I worked 12 hour shift with barely any thoughts. Just doing it. I didn't get tired, nor annoyed or exited. I got some physical pain, but I didn't find it bad or good for that matter. This is a little glimpse of ever present enlightenment. So I agree with you. We are all enlightened, but only enlightened ones know it :)
I must add, that "conditional enlightenment" is not enough. You need to practice a lot to get unconditional enlightenment and apply it in every aspect of life (most importantly, to help others).
