The answer
St. Isaac the Syrian relays to us his experience, saying, “When the spirit takes its dwelling-place in a man, he does not cease to pray, because the spirit will constantly pray in him. Then, neither when he sleeps, nor when he is awake, will prayer be cut off from his soul; but when he eats, and when he drinks, when he lies down, or when he does any work, even when he is immersed in sleep, the perfumes of prayer will breathe in his soul spontaneously.”314
