Perception.

 There is a story about Swami Vivekananda, the first yogi to come to the U.S. and Europe more than 100 years ago. While he was in Germany, he stayed with a well-known scholar. They happened to be conversing about a book on the table, which the scholar was speaking very highly about, and Vivekananda said, "Give me the book for an hour; let me see what is in it." The scholar felt insulted, "For an hour? What will you know in one hour? I have been reading this book for weeks and I'm not getting anywhere. And above all, it's in German. You don't know German, how will you read it?" Vivekananda said, "Give it to me for one hour."

Vivekananda took the book, placed it between his hands and sat there for an hour. Then he gave back the book and said, "There is nothing worthwhile in this book." The scholar thought this was arrogance. Vivekananda did not even open the book, it was in a language he did not know and he made a judgment about it. So he told Vivekananda, "This is nonsense." Then Vivekananda said, "Ask me anything about the book." The man said, "Okay, what is on page 663?" Vivekananda repeated it verbatim. He couldn't believe it, so he asked, "How is it that you know?" Vivekananda said, "That is why I'm Vivekananda." Viveka means "perception." His birth name is Naren, but his Guru named him Vivekananda because he is of such perception.

How did he arrive at this? Vivekananda is not reading the book; he is reading the one who wrote the book. He is reading the mind of the person who wrote the book itself. That is not intuition; this is a completely different dimension of perception.
