Just another way of saying.... when the waters of your life are rough.... sit quiet in your canoe

Try to be mindful and let things take their natural course.  

Then your mind will become still in any surroundings, like a clear forest pool.

 All kinds of wonderful, rare animals will come to drink at the pool, 

and you will clearly see the nature of all things. 

You will see many strange and wonderful things come and go,

 but you will be still. 

This is the happiness of the Buddha.
