'The Four Agreements' Author, Don Miguel Ruiz, And Oprah Talk About Being Impeccable With Your Word (VIDEO)

As author of the book "The Four Agreements," don Miguel Ruiz believes he has found four agreements that will help people live more authentic lives. One of the most important agreements, Ruiz tells Oprah in an episode of "Super Soul Sunday," is agreement number one: be impeccable with your word.

Being impeccable with your word -- that is, meaning what you say and following through without being flaky -- isn't just about going through the motions. Rather, it is a much deeper exercise and, therefore, a powerful way to change your life.

Reading from "The Four Agreements," Oprah quotes a passage that explains why this agreement is so powerful. "'Being impeccable with your word is the correct use of your energy. It means you use your energy in the direction of truth and love for yourself. If you make an agreement with yourself to be impeccable with your word, just with that intention alone, the truth will manifest through you and clean all the emotional poison that exists within you,'" she reads.

Oprah admits that even she has had trouble following this agreement, using her intent to work out as an example. "I had said to myself, 'I'm going to work out [for] 30 minutes,'" she says. "Then I got on the treadmill and I realized, 'Well, maybe I won't make it 30.'"

It's a challenge many people can relate to. "I am far more impeccable when it comes to other people than I am to myself," Oprah explains. "If I tell somebody I'm going to do something for them, I show up, I do it, no matter what. If I tell myself, 'I'm going to work out, I'm not going to eat that thing, I'm not going to do that anymore...' I am not as impeccable with myself. That's why this is such a powerful one. If you are impeccable with yourself, everything changes."

Ruiz agrees. "Whatever we want to change, first we need to start with ourselves," he says. "We cannot give what we don't have."

"Super Soul Sunday" airs Sundays at 11 a.m. ET on OWN.
