In her podcast, Liz Horowitz tells about how a single story in a book turned her on to Zen.
The book is called Zen Buddhism: an introduction to Zen with stories, parables, and koan riddles told by the Zen Masters - with cuts from old Chinese Ink Paintings. It was published in 1959 by the Peter Pauper Press, Mt. Verson, New York with no other information so the Peter Pauper Press gets the author credit.
Here's the book cover, the title page, and the brief story that turned her on all in one PDF.
