Do What?

Someone who is about to admonish another must realize within himself five qualities before doing so [that he may be able to say], thus:

"In due season will I speak, not out of season. In truth I will speak, not in falsehood. Gently will I speak, not harshly. To his profit will I speak, not to his loss. With kindly intent will I speak, not in anger."

-"Vinaya Pitaka," translated by F.S. Woodward
