What is written by every holy writer is written from his spiritual level (attainment) and from his practice (experience), in conformity with his level and practice. We must pay special attention to this point. Let us not be carried away and enraptured by a book written as if with fire that tells of high states and activities for which we are unfit. The reading of such a book, by firing the imagination, can harm us by communicating a knowledge of and desire for labours that are untimely and impossible for us. Let us apply ourselves to the book of a Father nearer to our state in the matter of attainment.
St. Ignatius (Brianchaninov)
