I have readed his book... there are some stuff I have a hard time understand, even though I can be sure to say this is probably the best meditation book I have ever read, it actually teaches you how to meditate....

Anyway, for those who have read his book, he offers samatha + vippasana combo practice if I am correct?

Maybe I have missed this,

but is practicing attention on the breath while having a peripheral vision of external distractions, a combo of samatha and insight practice? is practicing it that way brining insight and eventually leading to stream entry?

Thanks in Advance!
