Once having entered the stream and tasted liberation, you will not return ...The mind, the heart, will have turned, will have entered the stream, and it will not be able to fall back into suffering again. How could it fall?...It has entered the Way fully, knows its duties, knows its work, knows the Path, know its own nature. It lets go of what needs to be let go of and keeps letting go without doubting.
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 see clearly 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.
