Transpersonal psychology refers to Maslow's proposed fourth force in psychology that stresses the relationship between the individual and the cosmos or the universe and in so doing fo cuses on the mystical and spiritual aspects of human nature. Psychological approaches encouraging growth beyond an emphasis on the self are said to be transpersonal.
Transpersonal is called the fourth source of psychological theory, whereas psychoanalytic, behavioral, and humanistic are considered the first three types. Most often, the spiritual practices of transpersonal approaches stem from Eastern traditions and lead to an awareness of the interconnection among all forms of life.
