When reading books, our brain produces a stream of thoughts concerning what it is reading. On the path, our practice is suspension of thought in favor of watching over ourselves. Should one give up such reading at a certain point in one's development to help reduce the number of thoughts compounding the mind? Are these thoughts from reading a hindrance to one's advancement?
If you love a fine wine, or some extraordinary fruit, do you rush through the tasting of it? A true book is a rare wine, the fruit of centuries worth of knowledge distilled into a palatable, powerful food. If the time comes, and it will naturally do so, when you don't feel like reading, or no good work has fallen into your hands, then rest from reading. Otherwise, savor what moves you, roll its taste over in your heart and mind until it's time for the next impression.
