Behind the curtain you never knew was there, it is light.
The light is deepest black.
And laughter has its day.
(A snippet of description, describing Spiritual Enlightenment.)
The light is darkest black reminded me of this http://www.nonduality.com/dazdark.htm which I have posted before but I took this part out of it as it refers to the darkness.
"Moreover that wonderful “eternal life of everywhere” was still there, right behind my eyes—or more accurately, at the back of my head—continually recreating my whole personal body-mind consciousness afresh, instant by instant, now! and now! and now! That’s no mere metaphor for a vague sensation; it was so palpably real that I put my hand up to probe the back of my skull, half wondering if the doctors had sawn part of it away to open my head to infinity. Yet it wasn’t in the least a feeling of being damaged; it was more like having had a cataract taken off my brain, letting me experience the world and myself properly for the first time—for that lovely dark radiance seemed to reveal the essence of everything as holy.
I felt like exclaiming, “Of course! That’s absolutely right!” and applauding every single thing with tears of gratitude"
