Does the student of knowledge begin with the abridgments or the extensive works?

Do you advise the beginner student of knowledge to read the extensive works?
No, the beginner must stick to the abridgments. He should not confuse his mind so that matters become muddled for him. He must memorize the texts and review the accessible books that contain no difficulty, whose meaning is clear regarding the text and its reading. This is because if he enters the extensive books, matters will become muddled for him.
