equanimous

It was difficult to remain equanimous in the face of such preposterous impertinence.

With steady awareness of our inhalations and exhalations, the breath can become an equanimous constant through the ups and downs of our daily life.

Everything is cyclical and it pays to be equanimous at times of difficulty, but it is not worth to be happy about fire in someones' kitchen when your whole house is ablaze.
