10. I should like them to explain this, because it is a principal point, and because a soul, when our Lord begins to bestow these graces upon it, does not understand them, and does not know what to do with itself; for if God leads it by the way of fear, as He led me, its trial will be heavy, if there be no one who understands the state it is in; and to see itself as in a picture is a great comfort; and then it sees clearly that it is travelling on that road. The knowledge of what it has to do is a great blessing for it, so that it may advance forwards in every one of these degrees of prayer; for I have suffered greatly, and lost much time, because I did not know what to do; and I am very sorry for those souls who find themselves alone when they come to this state; for though I read many spiritual books, wherein this very matter is discussed, they threw very little light upon it. And if it be not a soul much exercised in prayer, it will find it enough to understand its state, be the books ever so clear. 11. I wish much that our Lord would help me to describe the effects on the soul of these things, now that they begin to be supernatural, so that men might know by these effects whether they come from the Spirit of God. I mean, known as things are known here below--though it is always well to live in fear, and on our guard; for even if they do come from God, now and then the devil will be able to transform himself into an angel of light; [4] and the soul, if not experienced herein, will not understand the matter; and it must have so much experience for the understanding thereof, that it is necessary it should have attained to the highest perfection of prayer. 12. The little time I have helps me but little, and it is therefore necessary His Majesty should undertake it Himself; for I have to live in community, and have very many things to employ me, as I am in a house which is newly founded--as will appear hereafter; [5] and so I am writing, with very many interruptions, by little and little at a time. I wish I had leisure; for when our Lord gives the spirit, it is more easily and better done; it is then as with a person working embroidery with the pattern before her; but if the spirit be wanting, there is no more meaning in the words than in gibberish, so to speak, though many years may have been spent in prayer. And thus I think it a very great advantage to be in this state of prayer when I am writing this; for I see clearly that it is not I who speak, nor is it I who with her understanding has arranged it; and afterwards I do not know how I came to speak so accurately. [6] It has often happened to me thus.
