good thoughts / good words / good deeds

good thoughts, good words, good deeds: That's the core ethical teaching of Zoroastrianism: Humata, Hukhta, Hvarshta in Avestan, the ancient Iranian language. It translates as good thoughts, good words, good deeds and represents the three pillars of the Zoroastrian moral framework, one of the oldest religions in the world, originating in ancient Persia (modern day Iran).

It's a remarkably simple and universal idea that ethics lives in thought, speech, and action equally.
