On our journey to the monastery you come upon a junction with three roads leading out, the left road, the middle road and the right road. There is a monk standing at the junction, who will truthfully answer any yes or no question, if he can do so without contradicting himself; otherwise he will immediately sit and meditate for eternity. The monk will only answer one question per traveler.
What question shall you ask of the monk to find out which road is the monastery road?
Hint: A monk saw a turtle in the monastery garden and asked his mentor, “All beings cover their bones with flesh and skin, so why does this being cover its flesh and skin with bones?”. The mentor took off one of his sandals and covered the turtle with it.
