Divine Qualities: Cleanliness

                                                                  Q. As a neophyte devotee, I need more clarification on the topic of keeping pets (dogs and cats). My family and I live on a farm in Durban, South Africa. The crime situation is rather serious here, in terms of the womenfolk being held up at their homes. I would like to know if there are any rules or regulations in terms of keeping dogs as a measure of security.

                                                                  Q. 1. If prasadam is spiritual why does it decay like normal food does in a day or so?
