Transcendental Meditation (TM) is a specific form of silent, mantra meditation and the organizations that constitute the Transcendental Meditation movement. Maharishi Mahesh Yogi created and introduced the TM technique and TM movement in India in the mid-1950s. The Maharishi taught thousands of people during a series of world tours from 1958 to 1965, expressing his teachings in spiritual and religious terms. TM became more popular in the 1960s and 1970s, as the Maharishi shifted to a more technical presentation, and his meditation technique was practiced by celebrities. At this time, he began training TM teachers and created specialized organizations to present TM to specific segments of the population such as business people and students. By the early 2000s, TM had been taught to millions of people; the worldwide TM organization had grown to include educational programs, health products, and related services. The TM technique involves the use of a silently-used sound called a mantra, and is practiced for 15–20 minutes twice per day. It is taught by certified teachers through a standard course of instruction, which costs a fee that varies by country. According to the Transcendental Meditation movement, it is a non-religious method for relaxation, stress reduction, and self-development. The technique has been seen as both religious and non-religious; sociologists, scholars, and a New Jersey judge and court are among those who have expressed views on it being religious or non-religious. The United States Court of Appeals upheld the federal ruling that TM was essentially "religious in nature" and therefore could not be taught in public schools. Most independent studies have found that the positive health outcomes attributed to the specific practice of TM do not exceed those resulting from other methods of stress reduction.

Humanistic psychology is a psychological perspective that rose to prominence in the mid-20th century in answer to the limitations of Sigmund Freud's psychoanalytic theory and B. F. Skinner's behaviorism. With its roots running from Socrates through the Renaissance, this approach emphasizes the individual's inherent drive toward self-actualization, the process of realizing and expressing one's own capabilities and creativity. Humanistic psychology helps the client gain the belief that all people are inherently good. It adopts a holistic approach to human existence and pays special attention to such phenomena as creativity, free will, and positive human potential. It encourages viewing ourselves as a "whole person" greater than the sum of our parts and encourages self exploration rather than the study of behavior in other people. Humanistic psychology acknowledges spiritual aspiration as an integral part of the psyche. It is linked to the emerging field of transpersonal psychology. Primarily, this type of therapy encourages a self-awareness and mindfulness that helps the client change their state of mind and behaviour from one set of reactions to a healthier one with more productive self-awareness and thoughtful actions. Essentially, this approach allows the merging of mindfulness and behavioural therapy, with positive social support. In an article from the Association for Humanistic Psychology, the benefits of humanistic therapy are described as having a "crucial opportunity to lead our troubled culture back to its own healthy path. More than any other therapy, Humanistic-Existential therapy models democracy. It imposes ideologies of others upon the client less than other therapeutic practices. Freedom to choose is maximized. We validate our clients' human potential." In the 20th century, humanistic psychology was referred to as the "third force" in psychology, distinct from earlier, less humanistic approaches of psychoanalysis and behaviorism. Its principal professional organizations in the US are the Association for Humanistic Psychology and the Society for Humanistic Psychology (Division 32 of the American Psychological Association). In Britain, there is the UK Association for Humanistic Psychology Practitioners.

The Human Potential Movement (HPM) arose out of the counterculture movement of the 1960s and formed around the concept of cultivating extraordinary potential that its advocates believe to lie largely untapped in all people. The movement took as its premise the belief that through the development of "human potential", humans can experience an exceptional quality of life filled with happiness, creativity, and fulfillment. As a corollary, those who begin to unleash this assumed potential often find themselves directing their actions within society toward assisting others to release their potential. Adherents believe that the net effect of individuals cultivating their potential will bring about positive social change at large.
