The fourth element of every spirituality concerns spiritual practice. No spirituality is vitally authentic and effective without some sort of spiritual discipline that is the means of inner growth in the attitudes, dispositions, habits, and commitments of the life of meaning, depth, and human maturity that is glimpsed in the best of religious consciousness. This point goes to the heart of the matter since spiritual practice is the factor of human effort in the work of our transformation. It is the living, transformative power of the inner reality taking form in a disciplined habit of relating to the divine or Ultimate Reality.
