When one is advanced in devotional service, while sleeping he also serves Krsna. That means twenty-four hours, satatam. Because in sleeping you also dream, so what we do during daytime we dream at night. So if one is cent per cent engaged in Krsna’s service, naturally he’ll dream also at night. I have seen one of our intimate relative. He was a businessman, selling cloth. So in a dream also he was quoting price of cloth. So that is natural. That is not unnatural. Therefore we have to practice. At the time of death, somehow or other if we quote the price of Krsna, then our life are successful. Therefore we should practice: Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare.
