I think you best learn these concepts from a competent teacher, preferably someone who walks the walk, and by putting them in practice, not by reading lots and lots of books with zero practice.<p>Besides, what the author doesn&#x27;t know is that concentration leads to mindfulness (never mind about proper or not), but mindfulness may not lead to concentration.<p>For me this is the best book on meditation out there: <a href="http:&#x2F;&#x2F;www.chanpureland.org&#x2F;publications&#x2F;chanhandbook&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.chanpureland.org&#x2F;publications&#x2F;chanhandbook&#x2F;</a> where you have very clear explanations of levels of concentrations (jhana or dhyana), how to pratice the basics on your own, etc. Also lots and lots of talks on youtube (or download) on Buddhist topics, as well as meditation  (non-religious).<p>I also learned personally the basics of meditation from their temple, and for sure they have real meditation skills. Unfortunately, for most us meditation has to be taught personally, it&#x27;s not something one can casually learn from some blog post, never mind finding the proper source.
