Reading of literary heritage

The literary heritage is within reach, but distant enough to tempt the reader and make it difficult for him. Between temptation and difficulty, there is room for the reader; so he can venture into its vastness. If he masters it, he will graze in its gardens. And in the midst of that grazing, he needs something to guide him to what he has hidden and to put his hand on what is concealed. On the way to the heritage, it is appropriate to place signposts; so that the reader may be guided by them; so his steps do not falter on rugged places, and he does not extinguish his ambition for what is sweet and cannot be guided by its lighthouse. And this book is an effort to place those signposts, which are indispensable, and some of which it is not appropriate to be ignorant of. Perhaps what has been written of them enables one to infer, so that one can reach the benefits and hint at the secrets, even though complete understanding and comprehensive insight are more precious than the white crow, and lack of understanding is a natural trait. We do not use it as an excuse to justify deficiency, but rather to strengthen ourselves in dismissing blame after exerting effort, reaching the goal of insight, and the one who reaches it is like a successful one.
