Both these locks open with the same key.
We should meet with triumph and Disaster with the same equanimity.
We should not pay back in the same way when we are being lied about or hated.
We should take both our victory and loss with the same equanimity.
To meet and to depart are two sides of the same coin.
Things do not remain the same for ever.
You and he are birds of the same feather.
He is constantly making the same mistakes.
