You can examine the continually changing emotions within
yourself, as they arise and cease. Even if you don't go astray by
chasing after these moods, perceptions and notions, you should
still carefully stabilize the mind so that it doesn't grasp after
anything — including any memory or thought which may arise. Just
concentrate on doing this and you will sweep clean the mind, wiping
out whatever suffering is present. Every condition arises and then
ceases, comes and disappears. Don't go and grasp hold of anything,
thinking it's good or bad, or taking it as oneself. Stop
all such thinking and conceptualizing. When you understand this,
the mind will calm down of itself; it will naturally become free.
Whatever thoughts arise, see that they just come and will go, so
don't grasp at them. Then there's not much else to do. Just
carefully scrutinize and detach yourself from any entanglements
within. There are then no fantasies and thought fabrications about
the past or future. They've all stopped. Things arise
and cease — just that.
"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."
