As a former Vipassana practicioner, I bought and enjoyed the Mental Development book. Short and to the point; helped me to start meditating again after several years of hesitation or a "dead end" of sorts. The tone and style of your writing have an interesting "math-y" feel -- but it also feels very clean and somehow calm.

Same goes for the Klong book, which I bought and enjoyed thoroughly. Haven't mastered the language, though, but I'm hoping to; it definitely is really interesting, especially for a person like me who loves the build-your-own-tiny-tools-with-tiny-languages-for-your-own-use-and-prefer-low-end-computers philosophy. I'm definitely a fan of your work; your webpage and entire way of life has been an inspiration for me for years already.

If you don't mind me asking -- are you working on any upcoming books these days as well?
