Just as the world can reveal itself as particles, the Tao
can reveal itself as human beings.
Though world and particles aren’t the same, neither
are they different
Worlds and particles, bodies and beings, time and
space:
All are transient expressions of the Tao.
Unseeable, ungraspable, the Tao is beyond any
attempt to analyze or categorize it.
At the same time, its truth is everywhere you turn.
If you can let go of it with your mind and surround it
with your heart, it will live inside you forever.
