There were formed seven 'double' letters: ת,ר,פ, כ;ד,ג,ב. Each has two voices, either soft or hard (spirantized or unspirantized). These are the foundations of Life, Peace, Riches, Beauty or Reputation, Wisdom, Fruitfulness, and Power. These are double, because their opposites take part in life, opposed to Life is Death; to Peace, War; to Riches, Poverty; to Beauty or Reputation, Deformity or Disrepute; to Wisdom, Ignorance; to Fruitfulness, Sterility; to Power, Slavery.
