Though the ancients described books to be “voluminous”, the world of books actually “makes those at the end of the world your neighbor”, which is by no means an idealistic analogy. There will never be any barriers even if the world becomes bigger. “Great Chiliocosm” mentioned by the Buddha can be deemed extremely enormous. As for the boundaries of the bookish world, there are “the present realm” “the past realm” and “the future realm”, which are all-embracing and time-crossing. Without leaving home, in the world of books we can not only experience at will, but also learn from masters at any time. Who says that readers are short-sighted, inflexible and indifferent to worldly affairs?
