Thanks, it&#x27;s on my kindle as well (haven&#x27;t finished it yet though).<p>As I see it, Culadasa is better suited both for general audience and for those more scientifically inclined - that&#x27;s why it seems to be ideal fit for HNers. It also seems to be much more ambitious, systematic work (it&#x27;s his opus magnum). Probably Shaila&#x27;s books target more advanced meditators - that&#x27;s not to say Culadasa is just for beginners.
