Self-Actualization and Self-Transcendence
Abraham Maslow amended his hierarchy of needs in 1969, adding self-transcendence as a motivational step beyond self-actualization. In self-actualization, a person seeks fulfillment of personal potential. Self-transcendence seeks to further a cause beyond the self, and may be motivated by a peak experience (see Euphoria). In a peak experience, the person may sense a profound mystical or aesthetic connection with the universe, and experience a sense of identity that transcends the personal self.
Self-transcendence is expressed through devotion to an ideal or cause, e.g., truth, scientific endeavor, assistance to others, human rights activism, or social justice.
