Mother Teresa’s General Letters to Her Sisters is a collection of Mother Teresa’s circular letters to the members of her religious congregation, the Missionaries of Charity Sisters. Not intended for those outside her community, they were written informally and spontaneously, often with little editing. It was for Mother Teresa a way of “being present” to the members of her rapidly expanding religious order. Seemingly of little interest except for those to whom they were addressed, the letters reveal the spiritual depth and pragmatic leadership of one of the most popular modern saints, as well as the inner dynamics underlying one of the most flourishing religious congregations of the last century. At the same time, and perhaps surprisingly, these letters may also prove to be worthwhile reading for a wider audience. Something of God’s wisdom and love seems to shine through Mother Teresa’s guidance and counsels, giving the reader light and help even though he or she is not living the same religious life as one of the Sisters. Mother Teresa’s unpolished statements are at times humble and at times humbling. They inspire confidence and encourage generosity. Many a time they are humorous but more often challenging. They are sprinkled with serene joy but also permeated with deep pain. She delighted in her Sisters’ accomplishments yet did not shy away from correcting even the smallest flaw, which didn’t escape her very observant eye. Sometimes she sounded just like a mother, full of tender loving care, and at other times more like a commander in chief, exhibiting an iron will and uncompromising determination. In either case, her followers seemed to have been drawn into the mystery of her charism, endeavoring to keep pace with her. Was it the attraction of what could be termed as her “leadership style” in the unremitting service of the poorest of the poor, or the perceived love of a mother’s heart that made her so unanimously loved and admired by the members of her congregation? Or was it both? The letters will reveal the answer! Inspiring in their simplicity, the letters may well serve as a treasure trove where anyone from a reflective scholar to a caring mother of a family may find satisfaction for their spiritual palate. The attractiveness of perennial truth often makes Mother Teresa’s presentation of traditional spiritual themes likewise relevant for contemporary needs. In the context of Mother Teresa’s statement that “we are created for greater things, to love and to be loved’,” these letters will help the reader discover and experience God’s presence through the little miracles of His love in one’s daily life. They will inspire us “to put our love into living action,” sharing His love with all those we meet, and so make our lives “something beautiful for God.”
