In India I observed practically every household washing (or having washed) their entrance in the morning and painting a kolam (a/k/a rangoli and many others) in front of the entrance.
I understand that a kolam is used to bring prosperity to the home. I did always wonder how people feel about stepping on these. I've seen kolam in front of entrances to houses, that were painted right on the sidewalk. Sometimes in a matter of minutes, the kolam would be smudged and hardly recognizable.
Is this not a problem, or is it just that having a kolam is better than having none, even if it is stepped on and smudged?
