Query: Too bad there isn't a hard copy

I wouldn't go so far as to say this is a farce, the man used to be blind for goodness sake! I think I would be more inclined to use it if it was in written form. Trying to find your way through the audio cassettes is difficult because you don't know what section he's talking about if you stop or roam the cassette. I kept wanting to skip certain parts but then got lost not knowing how far forward or back I should go. I just got discouraged. There is a decent length meditation/hypnosis type segment that didn't appeal to me, but maybe to others. He really stresses relaxing the eye instead of straining them on a daily basis which I think is such valuable information and really makes a difference. Just make sure you consider the advantages/disadvantages of an audio tape before you buy.
