When you walk into a massive cathedral, mosque, or shrine, leave an offering in the collection box as a way of expressing respect. The amount does not have to be much. The feeling behind it is more important. If no such collection box is present, there may be a nearby store that sells arts and crafts. In some cases, the same sentiments can be expressed by mailing a donation to an appropriate charity. Sacrifice of some kind is an ancient tradition in religious practice.
