It Will Pass

Once a student went to the Zen Master and said, "My meditation is horrible!! I feel so distracted.... my legs hurt... sometimes I fall asleep. It is just horrible!!"
 
The teacher replied, "Don't worry, it will pass."
 
A week later, the student came back to his teacher and said, "My mediation is wonderful!! I feel so aware, so peaceful, so alive. It is just wonderful!!"
 
The master replied, "Don't worry, it will pass."
