From Meredith J. Sprunger's introduction:
Spiritual psychology is the study and practice of mental processes relating to Ultimate Reality and Eternal values - truth, beauty, and goodness. It is concerned with the search for truth, the achievement of beauty, and the relationships of love. Spiritual growth is the key determiner of personality development and human destiny. Cultivating this aspect of our lives should, therefore, be the chief objective of our educational and developmental aspirations.
