The magnetism of the word is cultivated by speech, but it is controlled by silence. A talkative person may be interesting for some time, but afterwards he loses his magnetism; he has given it out by talking. Magnetism is also lost by speaking too low, or with too much emphasis, or with too high a pitch of voice. Magnetism is lost by every unnatural expression. When a cowherd calls his cows in a high-pitched voice, as is done in India, this is natural for him. He loses no magnetism, on the contrary he develops magnetism because it is natural for him to do so. But if a lawyer goes into a field and calls a cow in that same pitch he certainly loses magnetism, and the cow will not come either.
