Parable about the monk

One soldier guarding the road, stopped the Buddhist monk. Drawing his sword, warrior asked sternly traveler:

• Who are you? Where are going? And why did you go there?
  The monk thought for a few seconds, and then timidly asked:
• May I ask you a question?
• Ask - frowning, allowed a warrior.
• How much do you pay a week?
• Two baskets of rice.
• I'll pay you four baskets of rice, if you promise every day to ask me these questions.
