Sensei Michael gives a case on case fifty-nine of the Book of Equanimity: Seirin's Deadly Snake. In it, he speaks of the importance of surrender on the spiritual path - a way of being beyond knowing that causes us to be actualized by our lived experience.
Case #59 of the Shoyoroku – Seirin’s Deadly Snake:
Attention! A monk asked Master Seirin, “How about when a student proceeds on the trail?” Seirin replied, “The dead snake hits the great road. I advise you not to bump into it.” The monk said, “When it’s bumped into, then what?” Seirin answered, “You lose your life!” The monk continued, “When it’s not bumped into, then what?” And Seirin said, “There’s no place to dodge to.” The monk said, “At that very moment, then what?” Seirin replied, “It has been lost.” The monk then said, “I wonder where it’s gone.” And Seirin responded, “The grass is so deep there’s no place to seek.” The monk replied, “Shield yourself, Osho! Then you’ll be all right!” Finally Seirin clapped his hands and exclaimed, “Your poison is equal to mine!”
