Teresa de Cepeda y Ahumada - known as Teresa of Avila by millions over the last 500 years - lived in the 16th century, a time much like our own. It was the beginning of the modern era, and it saw a revolution in almost every aspect of life.
Teresa, a looming figure in the historic church, was one of the foremost writers on prayer. Her definition of prayer has been used for centuries by followers of Jesus:
Mental prayer [oración mental] is nothing else than a close sharing between friends; it means taking time frequently to be alone with him who we know loves us.
I find comfort in her most popularly known writing, a brief poem is known as her “Bookmark” (it was found in her prayer book after her death in 1582):
Let nothing disturb you,
Let nothing frighten you,
All things pass away:
God never changes.
Patience obtains all things.
He who has God
Finds he lacks nothing;
God alone suffices.
