In Afterzen, van de Wetering provides unorthodox solutions to a collection of classical koans found in Walter Nowick's The Wisteria Triangle. Van de Wetering gives them his own distinctive touch of humor, down to earth reality, and tough spirituality in the context of meeting and adventures with personalities "collaged from bits and pieces of teachers and fellow students who kindly came my way."

In this third book of the trilogy, van de Wetering is at his accessible, honest, funny, and genuinely spiritual best.
