The nature and vision of transpersonal psychology are discussed. Some historical perspectives are presented, followed by sections describing a vision of transpersonal psychology in terms of the following major themes: (a) the centrality of ego transcendence; (b} transpersonal actualization; (c) intrapsychic growth, including meditation and awareness, and transpersonal psychotherapy and problem solving; (d) potential contributions to psychological inquiry and epistemology; (e) happiness and emotions as examples of transpersonal perspectives on affective experiences. Other characterizations of the transpersonal vision are possible and desirable: the discipline of transpersonal psychology is still evolving, and its existential essence is open to perennial expression.
