Hi all!
There is an excellent bit in MCTB starting on page 221 where Daniel describes moving through the jhanas using the retina-burned afterimage of a candle flame as his object.
If you don't have a candle to hand you can achieve exactly the same thing using any bright light. I did this using the flashlight on my iPhone. Stare at the LED for 10 seconds or so, turn it off, then close your eyes and use the retina-burned afterimage as your object. I do this in a completely dark room so there are no distractions from other light sources when the eyelids start to flicker etc.
Please note the object (kasina) is the retina-burned afterimage, not the direct light itself which should be turned off once a decent afterimage is created.I have no idea if this level of brightness from the LED is bad for your eyes or not. I looked it up and there's not a lot on it, except an estimate of 5-10 lumens, and with it not being a laser I think 10 seconds might be all right.
-------------------------------
The first time I tried this it was an interesting experience but I did not get the cool visuals described in the book beyond the golden spinning star (which genuinely looks like a real sun).
On the second attempt, this time in a completely dark room, I got more of the visuals. I also fell asleep straight into a lucid dream after hitting what I believe was fourth samatha jhana. In the lucid dream I appeared to gain access to the unconscious's "master narrative" -- the ultra-condensed storyline it maintains about your character and direction of your life, filled with archetypes in the form of dream characters, all of which I hypothesized in an article I wrote a few months ago but which I had only ever dreamed non-lucidly. I believe major aspects of one's character can be changed by entering this narrative in a lucid dream and changing the archetypes and dream scenery, but I never really thought it would be possible to enter this narrative lucidly (I had only ever experienced it in non-lucid dreams up until this point). I appeared to this time but just had a good look around and even met the "caretaker" of my unconscious who showed me around as kind of tour guide!
I am continuing research into this idea and, as usual, am writing everything down as I go. I'm also treading carefully as I believe changing elements of this unconscious narrative could have potentially far-reaching and serious consequences for one's life.
On the third attempt with the kasina, I got practically every visual Daniel describes in the book. This included sparkling, fractal imagery within the "sun" itself and, when the sun faded and the outside edges of the "black hole" around the faded sun became the focus, I found they were made of coloured, beautiful fractals which looked basically identical to this: http://www.misterx.ca/FRACTALS/800px-Mandel_zoom_08_satellite_antenna.jpg
I found that image on the following page: http://www.misterx.ca/Mandelbrot_Set---Thumb_Print_of_God.html
Coined as the THUMBPRINT OF GOD, each MANDELBROT BUG is a near copy of the original, yet is an individual UNIVERSE unto itself with subtle and original variations. One could eXplore the above image FOREVER and still see new worlds. In fact, you can actually "zoom in" to the Set as seen above until the original image is larger than the UNIVERSE itself! Truly, it is an equation of INFINITY.
I could literally see infinite complexity in those fractals around the black hole in my visual field. Truly, you could not make this stuff up. The excitement of it all was nearly enough to break the jhana (this used to happen to me when first experiencing visuals) but I can hold things together pretty well now (and I get better at this seemingly exponentially every time I practise). I also noticed that the purple and green lines emanating around the black hole were made up of fractals themselves.
Studying these fractals was the last thing I remember because, suddenly -- BOOM! I was into what appeared to be a future-prediction vision. I saw a girl I haven't seen for ages in a bar I rarely go in. I'm quite often right when I have such visions, so I'm going to go to that bar on Friday to see what happens.
I woke up this morning with apparently a deep understanding of all things I turn my attention to. These ideas -- about people, concepts and themes -- drift around as kind of "whole images" in dimensions "interspersed" with our existing 4 dimensions, which are then interpreted by my logical brain as easy-to-understand rules and paradigm shifts.
Since getting this book I've had "clicks" and mini Dark Nights lasting a few hours or a few days, revolving around whatever I turn my attention to (the more personal importance the "thing" has to me, the longer the cycle), kind of like mini fractal versions of the Path of Insight.
I now believe any human change in understanding, on any topic, follows the Path of Insight in smaller or larger fractal versions of itself. Even the Path of Insight itself can be seen as just a change in understanding about something bigger than usual (the nature of reality itself) and therefore lasts longer (but needn't, once you grasp the territory) -- so the Path of Insight is just a larger fractal version of the changes in understanding we make about any little piece of our reality (an idea or thing) everyday in our day-to-day lives. Some new knowledge, such as finding the internet doesn't work that day, triggers a little Dark Night before the "reality" is adjusted in accordance with the new information.
I now believe that "everything is everything" (it's all just itself) and that everything is contained within everything else. I'm sure that didn't make much sense to many but hopefully some will understand.

Thanks Daniel for all your work!
