"You have created a teacher to wake you up. The teacher would not be here if you were not dreaming about the teacher. You have created a teacher out of your mind in order to awaken, to see that there is no teacher, no world - nothing. You've done this all by yourself."
This is convenient bullshit that sounds very profound, but in fact is just another theory that had an origin in time and space, and will pass away like all others.
Yes, emptiness is everywhere, inside and out, as well as objects, and ideas. Robert stated all were unreal because they were impermanent and that only the subject that was permanent. This is just another theory--one among thousands.
Don't limit yourself to this one "thuth," nor any others. But your own light, but don't go it alone until you have awakened. After awakening you can be your own light. Before that all is confusion, mystery, darkness.
