Course XVI - Teaching 6: The immortal Book

You can compare spiritual life with a long journey to the Holy City of God. So, the disciple must go forward and learn how to travel through it patiently and constantly, without return or deviation, always on a fixed route.
The Master has to be Divine Companion of his disciple. If the latter perseveres, he shall feel Him at his side, and shall hear His divine voice comforting him continuously.
During his anxious search, the disciple asks his Master:
“Eager for knowing, I seek intensely in books, magazines, lectures and classes of sages all that may be useful to my spiritual life. But all this is useless and just confounds and obstructs my mind.”
Say me, Master, where may I find those books that contain secrets about the progress and development of being? What book should I read, and where to find it in order to acquire knowledge and to progress more rapidly and efficiently?
“I am seeking, but I do not find. Instead of leaving me satisfied, several readings leave me dry and tired, and I do not find an official voice saying: “This is so and so. You need this”. Oh Divine Master, please say, which should be my readings, and which sciences should I devote myself to find you better. My whole aspiration is to be nearer to You and able to offer to you a pure heart and a clean mind.”
And the Master replies sweetly to his fervent disciple:
“Read healthy books, and give ear to words of eternal life.”
“Read about different religions and diverse philosophies, but do not be of anyone of them; you should have your own realization and philosophy, which are those that you have chosen since the beginning as foundation of the spiritual life; because all those things that you read and learn out of the Principle dictated by Me, are not the center of the spiritual life, but a corollary.”
“Read about lives of great men and heroes, but do not imitate anyone of them, because you have chosen Me alone as your unique model, for you have to be a new model, absolutely a new man, with your own exclusive characteristics, derived from a source of true vocation: spontaneity.”
“In the Divine Mother’s Temple I have prepared a book with golden letters to you, my faithful and attentive devotee.”
“My soul, be eager for this Book alone!”
Now the disciple remains calm, bows his head, and rests. A very sweet peace emanates from the lofty and lively blessing of his Master.
A human soul passes rapidly from one emotion to another and can never realize the reality through this veil. Imagination assimilates easily any reading and inserts a veil of fake reality; a good reader should be always like a guardian, who from his beacon focuses attentively the light over the waters in order to detect ships hidden amid shadows.
So, day by day, a new detachment emerges in the soul of the disciple; this detachment shall drive him away more and more from worldly books and concepts (also with fascinating variability) and shall make him approach the Eternal Book, that of the whole experience of the Divine Mother, at her Fatherland, definitive, unique and heavenly.
