The creation of St. John the Ladder, hegumen of the Sinai Monastery, called "Ladder, or Tablets of the Spirit," was written in the VI century as a saving guide to moral life. Although the book was created for the spiritual perfection of the monks of the monastery, any Christian living in the world can use it to get a reliable guide to the kingdom of heaven. This work of the Christian theologian, composed of thirty stages of improvement, is designed to teach a person how to deal with vices and passions, how to live piously and restore the image of God in his soul.
