Let nothing disturb you...

Let nothing disturb you,

Let nothing frighten you,

All things are passing away:

God never changes.

Patience obtains all things.

Whoever has God lacks nothing; 

God alone suffices.

Above from St. Teresa of Avila... I first encountered it before 1990 in the following version:

Let nothing disturb you
nothing frighten you.
All things are passing.
God never changes.
Patience obtains all things.
Nothing is wanting to him
who possesses God.
God alone suffices.
