Mahadeva made his instrument by the help of the human body and mind, considering its condition in the morning, in the midst of the day, in the afternoon, in the night, and at dawn when wakening. He found that at every time of the day and night a particular effect was made upon the human body and spirit and that a rhythm akin to that particular time must be prescribed psychologically and mystically in order to elevate the soul. And therefore a psychological science of music was made by Mahadeva, a science which was called "raga," which means "emotion," emotion controlled and utilized to the best purpose. When Parvati saw this instrument (Parvati was Mahadeva's consort), she said, "I must invent my vina." So she took half the part of the pumpkins and produced another kind of vina, the Saraswati vina. So there are two vinas: one is played by men, the other by women. On this instrument not only sharp and flat notes are produced, but also semitones. And in this way the music becomes rich, but to develop to the science of semitones is so difficult that it takes a lifetime. The musicians of India devote twelve hours of the day or more to the practice of the different rhythms, improvising on them. And in the end they produce a psychological effect which is not music, but magic, a magic that can thrill a person and that can penetrate the heart of man. It is a dream, a meditation, it is paradise. By hearing it one feels in a different world. Yet their music is hardly audible. Instead of playing before thousands of people, only one or two or three persons of the same quality and nature must be together to enjoy that music thoroughly. If a foreign element is present, the musician does not feel inspired.
