This article will share the intellectual journey E. Paul Torrance and I traveled in 2001, in which we explored psychology, science and ancient wisdom and traditions, including Native American and indigenous traditions, to establish a foundation for spiritual intelligence. This section will be followed by ways to develop and nurture spiritual intelligence in the classroom, focusing on service learning with student examples; a section on seven ways to develop or raise spiritual intelligence; a section examining efforts initiated and developed in business to develop spiritual intelligence; and servant leadership that incorporates much of what E. Paul Torrance and I called spiritual intelligence: "The capacity to use a multi-sensory approach, including intuition, meditation and visualization, to tap inner knowledge to solve problems of a global nature."
