The harmony of life can be learned in the same way as the harmony of music. The ear should be trained to distinguish both tone and word, the meaning concealed within, and to know from the verbal meaning and the tone of the voice whether it is a true word or a false note; to distinguish between sarcasm and sincerity, between words spoken in jest, and those spoken in earnest; to understand the difference between true admiration and flattery; to distinguish modesty from humility, a smile from a sneer, and arrogance from pride, either directly or indirectly expressed. By so doing the ear becomes gradually trained in the same way as in music, and a person knows exactly whether his own tone and word, as well as those of another, are false or true.

Man should learn in what tone to express a certain thought or feeling as in voice cultivation. There are times when he should speak loudly, and there are times when a soft tone of voice is needed; for every word a certain note, and for every speech a certain pitch is necessary. At the same time there should be a proper use of a natural sharp or flat note, as well as a consideration of key.

mirth - in a lively tone
grief - in a pathetic tone
fear - in a broken voice
mercy - in a tender voice
wonder - in an exclamatory tone
courage - in an emphatic tone
frivolity - in a light tone
attachment - in a deep tone
indifference - in the voice of silence.

An untrained person confuses these.

He whispers the words which should be known, and
speaks out loudly those which should be hidden.
A certain subject must be spoken in a high pitch, while
another requires a lower pitch.

One should consider the place, the space, the number of persons present, the kind of people and their evolution, and speak in accordance with the understanding of others, as it is said: "Speak to people in their own language."

With a child, one must have childish talk,
with the young, only suitable words should be spoken,
with the old, one should speak in accordance with their understanding.

In the same way there should be a graduated expression of our thought, so that everybody may not be driven with the same whip. It is consideration for others which distinguishes man from the animals.
