The first line:
Innocence: from the first, all must be
pervasive, gainful, and pure.
Those without such truth suffer calamity
and do not gain no matter where they go.
The second line:
No new fields, no old fields:
it is better to go far away.
The third line:
Unexpected trouble:
a cow might be tethered by someone else.
The traveler gains, the townsman loses.
The fourth line:
If you can be upright,
there will be no fault.
