"The sound that from another": between two warriors, the sound which is the fifth from the sound of one's own phoneme is a death-giver,
because the designation 'death' has been applied to the fifth. In the third, there is success in all actions. The remaining sounds bestow intermediate results. Between two warriors, death comes to the one whose sound in the name is lesser—that is, the one who has the lesser sound suffers death from the one who has the superior sound. When the rising sound is superior, victory occurs. When there is equality in the rising sound in the name, there is equality, peace, an alliance, and parity in victory and defeat. "In [the case of] the same sound": if both warriors have the same, first sound, the child, then in battle there is equality, parity. In the second, that is, when one has the rising of the child-sound and the other has the rising of the youth-sound, then there is half the fruit—that is, a slight victory for the youth. In the third, that is, when one has the rising of the child-sound and the other has the rising of the young-adult-sound, then the fruit is complete—that is, victory at every step for the young adult. In the fourth, when the fourth sound has risen, there is fear and defeat.
