If you were to spend an entire day without saying anything unnecessary, unhelpful, unkind, or untrue, would you speak more or less than normal?
The world is what it is largely because of the vibrational nature of the words released into its atmosphere. Spirits give rise to feelings, feelings in turn arouse thoughts, thoughts shape words, and words incite actions that change the world. There is discretion at every level, but at the end of the day, that which is created is significantly affected by the words we speak and write to one another.
Watch your words; change your world.
