The main point of the Handbook is that social activities and the human professions can gain a lot by employing a spiritual perspective. The essays of the Handbook show that spiritually grounded social practices can lead to better and more satisfying results than practices exercised on purely materialistic basis. Spirituality does not deny the importance of the material world and the material part of human existence but prioritizes the spiritual over the material. The primacy of the spiritual may catalyze substantial renewal of social practices which may brings more ecological, happier and peaceful being and functioning.
