Jayapataka Swami: One day Srila Prabhupada was saying that in Mayapur or Vrndavan, you get a thousand times benefit for any spiritual activity you do. So then he asked what is a thousand times zero? So the answer is zero. So we want to do as many spiritual activities as possible when we are in Vrndavan or Mayapur or some other holy dhamas so that it multiplies. Occupation in the holy dhamas means vacation from material activities that obstruct our spiritual activities.
