One day, I will write a substantive post on how I got into meditation. This is not that post. For now, you'll just have to take my interest in the topic as a given, and accept that, because of that interest, I found a momentary reprieve from the suffering of mindless internet surfing when I came across this post on SlateStarCodex.
One of the comments on the post (yes, I was reading the comments) led me to these two posts on the new Less Wrong: Kenshō and My attempt to explain Looking, insight meditation, and enlightenment in non-mysterious terms.
These are big threads, with lots of words. I won't claim to have read them all. Not yet. Still, I read enough to notice one book coming up as a reference multiple times: The Mind Illuminated by John Yates. It was held up as a comprehensive, non-mystical discussion of why and how to practice meditation.
I've been meditating fairly regularly (5-7 times a week) for a little over a year. The duration is a testament to the benefit I attribute to it. However, I have definitely reached a point where I am wondering where to go next and, perhaps occasionally, where it all leads. I hope that this book will prove useful on both fronts.
