O nightingale of the rose-garden of God! Singing melodies will bring animation and happiness to the world of humanity, the hearers will be delighted and joyful and their deeper emotions stirred. But this gladness, this sense of emotion is transitory and will be forgotten within a short time. However, praise be to God, thou hast blended thy tunes with the melodies of the Kingdom, wilt impart solace to the world of the spirit and wilt everlastingly stimulate spiritual feelings. This will last forever and endure the revolution of ages and centuries.
