I assert that I will employ the Art
which is its gift in Life's service
alone, rejecting all other usages.
I will guard growth and ease pain.
I will fight to preserve what grows
and lives well in its own way; and
I will change no object or creature
unless its growth and life, or that
of the system of which it is part,
are threatened. To these ends, in
the practice of my Art, I will put
aside fear for courage, and death
for life, when it is right to do so --
till Universe's end.
