Keep this in mind, for it is very important advice, so do not neglect it until you find you have such a fixed determination not to offend the Lord that you would rather lose a thousand lives and be persecuted by the whole world, than commit one mortal sin, and until you are most careful not to commit venial sins.
Teresa of AvilaThe custom of speaking to God Almighty as freely as with a slave - caring nothing whether the words are suitable or not, but simply saying the first thing that comes to mind from being learnt by rote by frequent repetition - cannot be called prayer: God grant that no Christian may address Him in this manner.
Teresa of AvilaHow often I failed in my duty to God, because I was not leaning on the strong pillar of prayer.
Teresa of AvilaDo not think you have gained a virtue unless you have first been tried by its opposite.
