Trace the stream back to its source.
Trace consciousness to the root
where there is no inside or outside,
Consciousness is,
I am over here as the subject,
you are all out there as objects,
and I roll along with my life.
But if I trace my mind back further,
to a place closer and nearer,
where I am no longer separating myself from objects,
the mind turns around.
With the backward step,
you see the unity
and the emptiness of separation.
Walking forward does not cease;
walking backward does not cease.
Walking forward does not obstruct walking backward.
Walking backward does not obstruct walking forward.
This is called the mountain flow and the flowing mountain.
