I think the author is speaking about a specific tradition of Buddhism, Zen, and is drawing parallels between that tradition and Quakerism. The “picking and choosing” point doesn’t make sense to me from that angle. Are you picking and choosing from Christianity when you talk about Protestantism, for example? His thoughts on Zen are pretty on point.

The author is ultimately speaking of a specific practice, meditation. A practice that predates Buddhism by probably more then a millennium. Zen is not relevant here as it is a latter development.
