A student went to his meditation teacher and said, "My
meditation is horrible! I feel so distracted, or my legs ache, or
I'm constantly falling asleep. It's just horrible!" "It will pass,"

back to his teacher. "My meditation is wonderful! I feel so aware,
so peaceful, so alive! It's just wonderful!' "It will pass," the
teacher replied matter-of-factly.
