Inner peace (or peace of mind) refers to a state of being mentally and spiritually at peace, with enough knowledge and understanding to keep oneself strong in the face of discord or stress. Being "at peace" is considered by many to be healthy (homeostasis) and the opposite of being stressed or anxious. Peace of mind is generally associated with bliss, happiness and contentment.

Peace of mind, serenity, and calmness are descriptions of a disposition free from the effects of stress. In some cultures, inner peace is considered a state of consciousness or enlightenment that may be cultivated by various forms of training, such as prayer, meditation, T'ai Chi Ch'uan or yoga, for example. Many spiritual practices refer to this peace as an experience of knowing oneself. Finding inner peace is often associated with traditions such as Buddhism and Hinduism.

Tenzin Gyatso, the 14th Dalai Lama, emphasizes the importance of inner peace in the world:

The question of real, lasting world peace concerns human beings, so basic human feelings are also at its roots. Through inner peace, genuine world peace can be achieved. In this the importance of individual responsibility is quite clear; an atmosphere of peace must first be created within ourselves, then gradually expanded to include our families, our communities, and ultimately the whole planet.

The Dalai Lama is a high lama in the Gelug or "Yellow Hat" branch of Tibetan Buddhism. The name is a combination of the Sino-Mongolian word далай (dalai) meaning "Ocean" and the Tibetan word བླ་མ་ bla-ma (with a silent "b") meaning "chief, high priest".

In religious terms, the Dalai Lama is believed by his devotees to be the rebirth of a long line of tulkus who are considered to be manifestations of the bodhisattva of compassion, Avalokiteśvara. Traditionally, the Dalai Lama is thought of as the latest reincarnation of a series of spiritual leaders who have chosen to be reborn in order to enlighten others. The Dalai Lama is often thought to be the leader of the Gelug School, but this position belongs officially to the Ganden Tripa, which is a temporary position appointed by the Dalai Lama who, in practice, exerts much influence. The line of Dalai Lamas began as a lineage of spiritual teachers; the 5th Dalai Lama assumed political authority over Tibet.

For certain periods between the 17th century and 1959, the Dalai Lamas sometimes directed the Tibetan government, which administered portions of Tibet from Lhasa. The 14th Dalai Lama remained the head of state for the Central Tibetan Administration ("Tibetan government in exile") until his retirement on March 14, 2011. He has indicated that the institution of the Dalai Lama may be abolished in the future, and also that the next Dalai Lama may be found outside Tibet and may be female. The Chinese government was very quick to reject this and claimed that only it has the authority to select the next Dalai Lama.

Wayne Walter Dyer (born May 10, 1940) is an American self-help author and motivational speaker.

Dyer was born in Detroit, Michigan, to Melvin Lyle (deceased) and Hazel Irene Dyer and spent much of his adolescence in an orphanage on the east side of Detroit. After graduation from Denby High School Dyer served in the United States Navy from 1958 to 1962. He received his D.Ed. degree in counseling from Wayne State University.^{[citation needed]}

Dyer worked as a high school guidance counselor in Detroit and as a professor of counselor education at St. John's University in New York City. He pursued an academic career, published in journals and established a private therapy practice. His lectures at St. John's, which focused on positive thinking and motivational speaking techniques, attracted many students. A literary agent persuaded Dyer to document his theories in his first book called Your Erroneous Zones. Although initial sales were thin, Dyer quit his teaching job and began a publicity tour of the United States of America, doggedly pursuing bookstore appearances and media interviews ("out of the back of his station wagon", according to Michael Korda, making the best-seller lists "before book publishers even noticed what was happening"), which eventually led to national television talk show appearances including Merv Griffin, The Tonight Show, and Phil Donahue.

Dallas Page (born Page Joseph Falkinburg, Jr.; April 5, 1956), better known by his ring name "Diamond" Dallas Page (DDP), is an American retired professional wrestler, fitness instructor and actor, signed to WWE in a Legends contract^{[citation needed]}. In the course of his wrestling career, which spanned two decades, Page has wrestled for mainstream wrestling promotions World Championship Wrestling (WCW), the World Wrestling Federation (WWF, now WWE), and Total Nonstop Action Wrestling (TNA).

Page first broke into the wrestling business in 1988, as a manager in the American Wrestling Association, where he worked for nine months before signing with WCW in 1991. There, he continued as a manager until late 1991, when he became a wrestler. Over a decade in WCW, Page became a three-time WCW World Heavyweight Champion, two-time WCW United States Heavyweight Champion, four-time WCW World Tag Team Champion and one-time WCW World Television Champion. He is the fourth WCW Triple Crown Champion.

After WCW was sold in 2001, Page signed with the WWF, where he became a one-time WWF European Champion and one-time WWF World Tag Team Champion. Due to a series of injuries, he allowed his contract with the company to expire in 2002. He worked for TNA from 2004 to 2005. Page is now an actor in small-budget films, as well as a fitness guru and motivational speaker.

Eckhart Tolle (German pronunciation: [ˈɛk.haʁt ˈtʰɔ.lə], English: /ˈɛ.kʰɑrt ˈtʰɒ.lə/; born 1948) is a German-born Canadian resident, best known as the author of the The Power of Now and A New Earth, which were written in English. In 2011, he was listed by the Watkins Review as the most spiritually influential person in the world. In 2008, a New York Times writer called Tolle "the most popular spiritual author in the [United States]."

Tolle says he was depressed for much of his life until he underwent, at age 29, an "inner transformation", then spent several years wandering and unemployed "in a state of deep bliss" before becoming a spiritual teacher. Later, he moved to North America where he began writing his first book, The Power of Now, which was published in 1997 and reached the New York Times Best Seller lists in 2000. Tolle settled in Vancouver, Canada, where he has lived for more than a decade.

The Power of Now and A New Earth sold an estimated three million and five million copies respectively in North America by 2009. In 2008, approximately 35 million people participated in a series of 10 live webinars with Tolle and television talk show presenter Oprah Winfrey. Tolle's books and teachings have stimulated much commentary from theologians and journalists. Tolle is not identified with any particular religion, but his work has been influenced by a wide range of spiritual teachings.
