The second in three posts from the Thai Forest Tradition, this one from their most influential teacher who has had a significant impact on Western mindfulness practice, through the many Western monks who trained under him.

Try to be mindful, and let things take their course.
Then your mind will become quieter and quieter in any surroundings

It will become still like a clear forest pool.
All kinds of wonderful and 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. Problems will arise and you will see through them immediately.
This is the happiness of the Awakened One.
