In order to keep harmony the Sufi even modulates his speech from one key to another; in other words, he falls in with another person's idea by looking at the subject from the speaker's point of view instead of his own. He makes a base for every conversation with an appropriate introduction, thus preparing the ears of the listener for a perfect response. He watches his every moment and expression, as well as those of others, trying to form a consonant chord of harmony between himself and another.

The attainment of harmony in life takes a longer time to acquire and a more careful study than does the training of the ear and the cultivation of the voice, although it is acquired in the same manner as the knowledge of music. To the ear of the Sufi every word spoken is like a note which is true when harmonious and false when inharmonious. He makes the scale of his speech either major, minor or chromatic as occasion demands, and his words - either sharp, flat or natural - are in accord with the law of harmony. For instance, the straight, polite and tactful manner of speech is like his major, minor or chromatic scale, representing dominance, respect and equality.

Similarly, he takes arbitrary or contrary motions to suit the time and situation by following step by step, by agreeing and differing, and even by opposing, and yet keeping up the law of harmony in conversation.

Take any two persons as two notes; the harmony existing between them forms intervals either consonant or dissonant, perfect or imperfect, major or minor, diminished or augmented, as the two persons may be.

The interval of class, creed, caste, race, nation or religion, as well as the interval of age or state of evolution, or of varied and opposite interests shows the law here distinctly.

A wise man would be more likely to be in harmony with his foolish servant than with a semi-wise man who considers himself infallible.
Again it is equally possible that a wise man be far from happy in the society of the foolish, and vice versa.
The proud man will always quarrel with the proud while he will support the humble.
It is also possible for the proud to agree on a common question of pride, such as pride of race or birth.
