Elizabeth McGovern said she would love to have the 'grace and dignity' of her Downton Abbey character, but she has too much 'anger'.
The star, whose grandfather was a Buddhist, said a quiet life was not for her.
Elizabeth, 52, told Reader's Digest: "When I do get time off, I'm way too busy going to the supermarket and cooking the family dinner to go and live in a monastery. And I'm probably too angry to meditate."
The American actress, who plays Lady Cora, the Countess of Grantham, in the hit ITV costume drama said she enjoyed the success of the show, but it did not stop her 'getting cross at some of the things I see'.
She said: "I'm not trying to paint a picture of some terrible personality disorder, but you ask anyone who really knows me and they'll tell you they see a lot of anger.
"Look at the way we treat the world and let each other down. The unfairness of life. I'm not necessarily talking about my life, because I get compensated very well for my job, but that doesn't stop me getting cross at some of the things I see.
"I'm not proud of it, because anger is not useful. I'd love to be able to handle life with Cora's grace and dignity. But hey, that's just how it is. I try my best in life and I'll keep trying."
