do not injure any being...

In what is seen, there should be just the seen;
In what is heard, there should be just the heard;
In what is sensed, there should be just the sensed;
In what is thought, there should be just the thought.

...
He should not kill a living being, nor cause it to be killed, nor should he incite another to kill.
Do not injure any being, either strong or weak in the world.
