Spirituality I take to be concerned with those qualities of the human spirit--such as love and compassion, patience, tolerance, forgiveness, contentment, a sense of responsibility, a sense of harmony, which bring happiness to both self and others. While ritual and prayer, along with questions of nirvana and salvation are directly connected with religious faith, these inner qualities need not be, however. There is thus no reason why the individual should not develop them, even to a higher degree, without recourse to any religious or metaphysical belief system. This is why I sometimes say region is something we can perhaps do without. What we cannot do without are these basic spiritual qualities.
