I saw the ideas presented as one of a long stream of similar ideas which have been presented, all of which shape a narrative that obscures more than it reveals. I happened to make a comment on this instance. It's great that you don't see a conflict or have any issues with the ideas presented...I'm a different person.
One thing that's happened regarding Buddhism is that western people have picked up the things they like and ignored the rest. In reality, Buddhists think that the experience of Oneness that they reach is real. They may give it different names. But I haven't heard it said by them that the experience is limited to the mind (by which you must mean an individual brain in a head). I think western "apologists" for Buddhism have done that, in order to curry favor...to win over a handful of materialists.
They are wasting their time. A materialist is already someone who staked out the least courageous position of engagement in life. What good is their approval?
