Smoke will not do

"So pure devotional service is the flame. All other things are smoke. You must get the flame. Otherwise your business will not get done. So, naturally, we fan when there is smoke, phat-phat-phat. As soon as flame comes, there is no smoke. So again fan it, let the flame come. Then everything will be all right. Otherwise be satisfied with the smoke. You are cooking with smoke for three hundred years." - Srila Prabhupada
