Three yogis are performing a meditative vigil in a cave high in the
Himalayas. One day there is a sound outside of the cave. Six months later
one of the yogis says, “that was a tiger.”

The cave is silent once again. About a year later, another yogi says, “that wasn’t a tiger it was a lion.” Again the cave falls silent. About two years later the third yogi says, “If you two don’t stop arguing I’m leaving.”
