There was a great king. The story goes the king gave his wise men the task of making a special ring which, when he looked at it, would make him unhappy when he was happy, and the ring would also, when he looked at it, make him happy when he was unhappy.
This was very unusual so the wise men worked hard because they wanted to please the king and not be thrown out for being worthless servants. They worked day and night and finally presented to the king a ring which had the following inscription on it: This too will pass.
The tao says there are three responses to truth.
The lowest response is laughter when truth is asserted.
The second type is intellectual and the mind makes philosophy out of it.
The third type opens the mind and one steps through a mental door with a deep understanding and the body throbs with an unknown adventure and enters a new world.
