Tongue is the entry point of your food and exit point of your thoughts.

Tomorrows thoughts cannot be thought today.

People of the same community don't have the same thoughts, our different thoughts and feelings makes us unique.

Give thy thoughts no tongue.

Break, break, break, On thy cold gray stones, O sea! And I would that my tongue could utter The thoughts that arise in me

Keep thy tongue from evil, and thy lips from speaking guile.
