His constant fight is with the Nafs (self-interest), the root of all disharmony and the only enemy of man. By crushing this enemy man gains mastery over himself; this wins for him mastery over the whole universe, because the wall standing between the self and the Almighty has been broken down. Gentleness, mildness, respect, humility, modesty, self-denial, conscientiousness, tolerance and forgiveness are considered by the Sufi as the attributes which produce harmony within one's own soul as well as within that of another.
