If we do not use the creating power of the universe to realize our wishes, it will not be of much use, no matter what we pray for. The sound stream is the material and the creating power of the universe. We can use it to create both heaven and hell; therefore, we should be discreet and make use of this material to create good things, thus bringing peace to the world.
There's nothing wrong in the saying "everything is created by the mind". However, without the material, we can only create fakes; only with the material can we create the real thing. The Bible says that the sound is the power of creation, and only by using the sound can we create a real world. Only through practicing the Quan Yin Method can our dreams come true and can there truly be heaven and the West Paradise.
