I only discovered Thanissaro this last week. By accident I ran across a dharma talk of his on youtube about how the mind is trying to kill you.
Since then I've been on a Thanissaro podcast marathon, and I'm almost finished with his book on rebirth (written it seems as a thoughtful answer to Stephen Bachelor's "Confession of a Buddhist Atheist).
At first I asked myself, "Where has this guy been? Why didn't I discover him earlier?" Then I realized that it was only at this point in my journey, after developing a basic enough understanding of the dharma to have questions about it, that his explanations could be relevant to me.
All his materials, ebooks and podcasts, are offered free of charge at the site: http://www.dhammatalks.org/index.html
I am thankful for his teaching.
I must donate to the Metta Forest Monastery and support this work.
