Teresa of Ávila was a Carmelite nun, Spanish mystic, religious reformer, author, theologian, and Doctor of the Church. She lived her life as an active faithful during the Catholic Reformation, initiating a major change in the Carmelite orders which later on led to the establishment of the Discalced Carmelites.
When it comes to her writings, Teresa of Avila is being recognized for her outstanding works about Christian mysticism and Christian meditation practice. Even up to this day, her writings are being sought by people from both within and outside the Catholic community. In fact, her two most popular works, The Life of Teresa of Jesus and The Interior Castle, remains to be recognized as an integral part of Spanish Renaissance literature.
Teresa died in October 1582. Forty years after her passing, she was canonized by Pope Gregory XV. However, it was not until the 27th of September 1970 when she was proclaimed as the first female Doctor of the Church by Pope Paul VI.

Today, St. Teresa of Avila is widely acknowledged for her works that continue to inspire Christians, philosophers, theologians, historians, neurologists, fiction writers, and artists. Her memorial day is celebrated today, October 15th.
Prayer to St. Teresa of Ávila
O Saint Teresa, seraphic Virgin, beloved spouse of thy crucified Lord, thou who on earth didst burn with a love so intense toward thy God and my God, and now dost glow with a brighter and purer flame in paradise: obtain for me also, I beseech thee, a spark of that same holy fire which shall cause me to forget the world, all things created, and even myself; for thou didst ever avidly desire to see Him loved by all men.
Grant that my every thought and desire and affection may be continually directed to doing the will of God, the supreme Good, whether I am in joy or in pain, for He is worthy to be loved and obeyed forever. Obtain for me this grace, thou who art so powerful with God; may I be all on fire, like thee, with the holy love of God. Amen.
