In 1580, when St. Teresa was sixty-five years old, the Church allowed the Carmelites to split into two groups, the Calced and Discalced. Two years later, her health broken, Teresa died on October 4th. St. Teresa's Feast day is October 15. The following prayer was found after St. Teresa's death, written on a card in her breviary. Let nothing frighten you.
Patience gains all things.
Who has God wants nothing. God alone suffices.
