I would have to say the people in that book aren't quite being fair to the five senses. The 5 senses are the tool of the eye of flesh. We can use the senses to catogorize things, which in earlier development was a huge accomplishment. Even when using the eye of mind(reason, logic, etc) many of it's greatest uses are grounded in the eye of flesh(5 senses). The Zen people expand their eye of contemplation(spiritual, "third eye") with meditation and other spiritual practice. But because of that they shouldn't reduce "reality" or material things to that eye. Material things are made sense of by the eye of flesh, so when dealing with such things, it is the best to use and is very very important, even if it is lower in development than the eye of mind, or contemplation.
cliff notes: The 5 senses are what should be used to deal with material things, not anything spiritual(unless it is using the 5 senses to the extent they should be) If you don't see, smell, hear, or even feel a bullet going through your brain, you are still going to die.
