Whoever has not begun the practice of prayer, I beg for the love of the Lord not to go without so great a good. There is nothing here to fear but only something to desire.
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 AvilaGranting that we are always in the presence of God, yet it seems to me that those who pray are in His presence in a very different sense; for they, as it were, see that He is looking upon them, while others may go for days on end without even once recollecting that God sees them.
