LET every thought thy lips would utter pass three gates of gold, -
But, if through these it fails to pass, then let it not be told ;
And o'er each gate in silver letters written thou wilt find,
Above the first one, "Is it true?" the second, "Is it kind ?"
And "Is it necessary?" o'er the third one and the last.
Then guard thy thoughts, let none escape,
save those these gates have passed
