The busy mind cannot meditate.
We should do our work no matter the outcome.
Desires come and go.
We do not get anything in this world; nor do we take anything.
You are not the only one suffering.
Whatever happened, happened for good. What is happening is happening for good. What will happen, will happen for good.
Be moderate in everything.
The world expires, and someday, someday will also come.
Anger leads to misjudgment.
The soul is immortal and the body perishes. But the soul never dies.
