St. Teresa of Avila
Autobiography
Chapter XXXVI · Part 5 of 5
31. This is to be the perpetual aim of those who are here, to be alone with Him alone. They are not to be more in number than thirteen: I know this number to be the best, for I have had many opinions about it; and I have seen in my own experience, that to preserve our spirit, living on alms, without asking of anyone, a larger number would be inexpedient. May they always believe one who with much labour, and by the prayers of many people, accomplished that which must be for the best! That this is most expedient for us will be seen from the joy and cheerfulness, and the few troubles, we have all had in the years we have lived in this house, as well as from the better health than usual of us all. If any one thinks the rule hard, let her lay the fault on her want of the true spirit, and not on the rule of the house, seeing that delicate persons, and those not saints,—because they have the true spirit,—can bear it all with so much sweetness. Let others go to another monastery, where they may save their souls in the way of their own spirit.
