It's possible there is something in our culture that tilts us in this direction. Comparative studies in cognitive psychology have shown that Westerners do tend to have a more analytical mind than more holistically-minded East Asians. Although all stereotypes are suspect, the image of a Westerner whose primary relationship to the Dharma is through reading (or writing) books about it is not without some basis in reality.
Or maybe it's not really a Western thing -- just a human thing. Every religion has its adherents who have studied the founder's teachings in great depth but still seem to be clueless about their basic meaning. Fundamentalist Christians can quote the Bible chapter and verse while holding signs saying "God Hates Fags," but they seem to forget that Jesus primarily taught tolerance, understanding, forgiveness and love of one's neighbor. Jihadists can memorize the whole Koran, but use its words of wisdom to rationalize mass murder. And Buddhist scholars can debate absolute and relative truth and quote Nagarjuna and Chandrakirti and the Buddha on the subtle meaning of emptiness, but their personal lives might remain a mess and their relationships can be as devoid of compassion as any drunk on the street.
Of course, studying the Dharma and developing conceptual knowledge of it is an essential element of the path. In Tibetan Buddhism, it is often depicted as one of the three wheels: study, meditation, and action. Yet it seems that study is frequently overemphasized at the expense of the other two wheels. When we fall into this trap, we might develop a lot of very refined concepts about enlightenment, yet we may not understand what it means to actually live in an enlightened way. Scholars of Buddhism can, and often do, have an intimidating level of erudite and sophisticated knowledge about the Dharma, and yet they can, in some cases, remain apparently clueless about what it means to actually live the Dharma.
Recently I said to a friend: "Concepts about enlightenment are like books about dancing." (I was paraphrasing this line from a Buddhist teaching I saw somewhere, but I can no longer recall where.) No matter how well-written or well-researched a book about dancing might be -- even if it is written by the most accomplished dancer -- by itself it can never convey or bring about the actual experience of dancing. For a professional dancer, there is a certain value in studying the history and theory of dance, but no amount of theory alone can actually make one a good dancer. Only practice and action can do that.
Naropa, one of the Indian mahasiddhas revered by Vajrayana Buddhists, was a great, accomplished scholar at Nalanda University in ancient India. One day as he was poring over one of his texts in the library, a shadow fell over the page. He looked up to see an old hag standing next to him. In her croaking voice, she asked him, "What are you reading, Naropa? Do you understand the words or the meaning?"Naropa replied, "I understand the words I am reading." At this, the old hag became gleeful, and danced around laughing. Naropa wasn't sure why his response had made her so happy, and so he added, "I understand the meaning too." At this, the hag stopped dancing and grew morose, and began to cry. Confused by this schizoid behavior, Naropa asked, "Why are you crying? And why were you so happy when I said I understood the words?"
"When you said you understood the words, you were telling the truth," said the old hag, "and that made me very happy. But when you said you understood the meaning, you were lying. You and I both know you don't understand the meaning. And that made me very sad." With this, the hag vanished, but this encounter was said to be the spark that led Naropa to seek out his guru Tilopa and attain genuine realization of the teachings rather than mere intellectual understanding of them.
Like most stories about the mahasiddhas and saints, the story of Naropa and the hag is perhaps best regarded not as a historical account but as hagiography (pun intended) -- a teaching tool in symbolic or narrative form that contains a valuable lesson for each of us. The story of Naropa and the hag is a cautionary tale, a reminder that academic study of the Dharma, like books about dancing, is useful up to a certain point, but useless beyond that point. There comes a time in the life of every spiritual aspirant when you simply need to set the books aside and step out on the dance floor, and live the Dharma. That is the only way to realize the meaning of what you're studying.
