Bring Me the Rhinoceros: And Other Zen Koans That Will Save Your Life By John Tarrant. Shambala, 2008.
I haven't finished this, and it will take me a while to do so, a few pages at a time. But I think this is a fine little volume that I unhesitatingly recommend. For a long time I have been powerfully attracted by what little I know of "zen," and over the years books by both Suzukis (D.T and Shunryu) have been of inestimable value to me. I am finding this book more useful even than Tarrant's earlier The Light Inside the Dark.
