I just realized I need a different type of computer with CD rom function to listen to the Brainwave Generator in MAP. Is this neeeded and/or a deteriment to effort in vain, or will I succeed with just the text and exercises? I wonder and ask has anyone succeeded without listening and reading only? I won't give up because of not being able to listen, yet I will continue. It's like I have an engram telling me I can't achieve witthout it, so please at least give me a yes or no to go by. Perhaps I will ask Jesus to help me. Have a blessed day! Good luck to all aspiring astral projectors.
