Similarly, if at any given moment of our prayer or meditation we experience more relish and devotion than at another, we should pause as long as this affection lasts, even though it continue during the whole time of our recollection.  As we have said, the purpose throughout is devotion, and it would be a mistake, in consequence, to seek elsewhere, and with doubtful hope of success, what we already hold securely in our hands.  –St Peter of Alcantara ‘Treatise on Prayer & Meditation’

A Bird in the hand is worth two in the bush.
