A mantra, if performed incorrectly, can bring on madness quickly. But many who uttered the Name without discipline were saved. Other syllables cause harm if spoken carelessly, yet one who takes the Name even in sleep is liberated. If melody, knowledge, or rhythm go wrong, there may be delay, but the Name is auspicious at all times. Other forms of worship have prohibitions, but the Name may be spoken by all, without restriction. Says Tuka, austerities cause people to stumble and fall, but the Name alone uplifted even the courtesan.
