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.

Spiritual progress is the changing of the point of view.

Now if I do anything it is to tune souls instead of instruments. To harmonize people instead of notes. If there is anything in my philosophy, it is the law of harmony: that one must put oneself in harmony with oneself and with others.

Peace is perfected activity.

He who gives love will receive a thousandfold in return.

The wonderful thing is that the soul already knows to some extent that there is something behind the veil, the veil of perplexity, that there is something to be sought for in the highest spheres of life, that there is some beauty to be seen, that there is Someone to be known who is knowable.

People in the world wish to make things rigid, things which are of the finest nature which words cannot explain. When a person describes the hereafter, it is just like wanting to weigh the soul or photograph the spirit. I personally think that you must be able to realize yourself what the hereafter is. You must not depend upon my words.
