one produces two,
two produce three,
three produce all beings:
42.2 all beings bear yin and embrace yang,
with a mellowing energy for harmony.
42.3 The things people dislike are
only to be alone, lacking, and unworthy;
yet these are what monarchs call themselves.
42.4 Therefore people may gain from loss,
and may lose from gain.
42.5 What others teach,
I also teach.
The strong cannot master their death:
I take this to be the father of teachings.
