One of her best-known pieces of writing is her "bookmark", nada te turbe, which translates as:
Let nothing disturb you,
nothing frighten you,
All things are passing;
God never changes.
Patience obtains all things.
Whoever has God lacks nothing;
God alone is enough.
It is, in a way, a prayer of two parts: a call to trust, with the reassurance of the certainty and permanence of God, followed by the reminder that this God is all we need. And whenever I hear it I am reminded of a prayer by Julian of Norwich, a mystic who died about a hundred years before Teresa's birth, but whose spirituality and writings are equally timeless:
God, of your goodness, give me yourself; you are enough for me, and anything less that I could ask for would not do you full honour. And if I ask anything that is less, I shall always lack something, but in you alone I have everything.
Teresa's legacy is alive in the Carmelite family around the world, especially the women who live her spirit and rule in a diversity of ways, as can be seen in this international virtual choir singing a new arrangement of nada te turbe. The song is beguilingly beautiful, reminding us that beneath the starkness and struggle of absolute trust and God alone, lies a well of deep serenity and joy. May Teresa - and Julian - pray for us, that we may know the truth of this in our hearts and our lives.
