Mother Teresa was recently recognized as a Saint. The process of canonization (becoming a saint) involves the performing of a miracle. From Wikipedia:
If the Venerable was not a martyr—all non-martyrs are "confessors" as they "confessed" or bore witness to their faith by how they lived their lives—it must be proven that a miracle has taken place by his or her intercession: that is, that God has shown a sign that the person is enjoying the Beatific Vision by God performing a miracle in response to the Blessed's prayers.
The first such miracle results in the person's beatification, recognized with the title "Blessed". The second such miracle results in the person's canonization, recognized with the title "Saint".
What were the miracles that were performed during the beatification and canonization processes of Mother Teresa?
