Interior Castle or The Mansions

SAINT TERESA began to write the Interior Castle on June 2, 1577, Trinity Sunday, and completed it on the eve of St. Andrew, November 29, of the same year. But there was a long interruption of five months, [1] so that the actual time spent in the composition of this work was reduced to about four weeks--a fortnight for the first, and another fortnight for the second half of the book. The rapidity with which it was written is easily explained by the fact that the Saint had conceived its plan some time previously.
