Gandhi talked about our thoughts (very similar to Lao Tzu’s words below),
Lao Tzu, “Watch your thoughts; they become words.
Watch your words; they become actions.Watch your actions; they become habits.
Watch your habits; they become character.
Watch your character; it becomes your destiny.
“Your beliefs become your thoughts; Your thoughts become your words; Your words become your actions; Your actions become your habits; Your habits become your values; Your values become your destiny.” Gandhi
Buddha has very similar words as well in a very loving way,
“The thought manifest as the word. The word manifests as the deed. The deed develops into habit and the habit hardens into character. So watch the thought and its ways with care. And let it spring from love born out of concern for all beings.”
