Spirituality refers to an ultimate or an alleged immaterial reality; an inner path enabling a person to discover the essence of his/her being; or the "deepest values and meanings by which people live."Spiritual practices, including meditation, prayer and contemplation, are intended to develop an individual's inner life; spiritual experience includes that of connectedness with a larger reality, yielding a more comprehensive self; with other individuals or the human community; with nature or the cosmos; or with the divine realm. Spirituality is often experienced as a source of inspiration or orientation in life. It can encompass belief in immaterial realities or experiences of the immanent or transcendent nature of the world.

Traditionally, many religions have regarded spirituality as an integral aspect of religious experience. Among other factors, declining membership of organized religions and the growth of secularism in the western world have given rise to a broader view of spirituality. The term "spiritual" is now frequently used in contexts in which the term "religious" was formerly employed; compare James' 1902 lectures on the "Varieties of Religious Experience".

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.
