Lessons in the Fundamentals of Go - Kageyama Toshiro

The book’s main themes are the importance of fundamentals, the philosophy of go, and how to study. It should be read deliberately, a chapter a day at the fastest, and a fortnight to finish the whole book. If the reader will then spend another fortnight rereading it and learning from it as he would from a good instructor, I think I can promise that he will surmount the barrier of his present rank.
