It was recently reported that Mother Teresa's letters revealed she sometimes doubted God's role in the work of the congregation.
The collection of letters written to colleagues and superiors over 66 years were compiled by her postulator. They will soon be published.
Sr Nirmala said: "She suffered, yet she had a mask on herself of mysterious joy which comes only from complete surrender to God."
Sr Nirmala succeeded an ailing Mother Teresa six months before she died aged 87 this day ten years ago. Today she will be present at a memorial mass.
