This explains the difference of the "Life" such as we know it from the first version or the "Relations" preceding it. Whatever this writing was, it still belonged to the period of her spiritual education, whereas the volume before us is the first-fruit of her spiritual Mastership. The new light that had come to her induced her confessors [25] to demand a detailed work embodying everything she had learned from her heavenly Teacher. [26] The treatise on Mystical theology contained in Chapters X. to XXI., the investigation of Divine locutions, Visions and Revelations in the concluding portion of the work could have had no place in any previous writing. While her experiences before she obtained the Gift of Wisdom influenced but three persons (one of them being her father), a great many profited by her increased knowledge. [27] The earlier writings were but confidential communications to her confessors, and if they became known to larger circles this was due to indiscretion. But her "Life" was written from the beginning with a view to publication. Allusions to this object may be found in various places [28] as well as in the letter appended to the book, [29] but the decisive utterances must be sought for elsewhere, namely in the "Way of Perfection." This work was written immediately after the "Life," while the Saint was as yet at the convent of St. Joseph's. It was re-written later on and is now only known in its final shape, but the first version, the original of which is preserved at the Escurial and has been reproduced photographically, leaves no doubt as to the intentions of St. Teresa in writing her "Life." "I have written a few days ago a certain Relation of my Life. But since it might happen that my confessor may not permit you (the Sisters of St. Joseph's) to read it, I will put here some things concerning prayer which are conformable to what I have said there, as well as some other things which appear to me to be necessary." [30] Again: "As all this is better explained in the book which I say I have written, there is no need for me to speak of it with so much detail. I have said there all I know. Those of you who have been led by God to this degree of contemplation (and I say that some have been led so far), should procure the book because it is important for you, after I am dead." [31] At the end she writes: "Since the Lord has taught you the way and has inspired me as to what I should put in the book which I say has been written, how they should behave who have arrived at this fountain of living water and what the soul feels there, and how God satiates her and makes her lose the thirst for things of this world and causes her to grow in things pertaining to the service of God; that book, therefore, will be of great help for those who have arrived at this state, and will give them much light. Procure it. For Father Domingo Bañez, presentado of the Order of St. Dominic
