Without freedom of thought, there can be no such thing as wisdom - and no such thing as public liberty without freedom of speech.
'As I am, so are they; as they are, so am I.' Comparing others with oneself, do not kill nor cause others to kill.
Delight in heedfulness! Guard well your thoughts!
Speak only endearing speech, speech that is welcomed. Speech, when it brings no evil to others, is a pleasant thing.
The thing that is disliked by me is also disliked by others. Since I dislike this thing, how can I inflict it on someone else?
'As I am, so are these. As are these, so am I.' Drawing the parallel to yourself, neither kill nor get others to kill.
All tremble at violence; all fear death. Putting oneself in the place of another, one should not kill nor cause another to kill.
Ceasing to do evil, Cultivating the good, Purifying the heart: This is the teaching of the Buddhas.
No one is useless in this world who lightens the burdens of another.
