What is MENTORSHIP?

I was talking with a successful business owner not that long ago when the topic of our conversation turned to Mentorship. They said that they felt they had been 'mentored' by a number of people through the use of Books, DVD and CD educational materials.  While not disputing the value of resources like this as a part of the learning process, I admit that I struggled with the concept of these resources being a substitute for a personal mentoring relationship. So I put the question out to you for comment. What are your thoughts, your reaction or experience related to this suggestion?
