Try thinking of it like a gps that remembers how you got to the house and where it is. When you leave the house, you can get back to it, no matter where you go.

You very well might think about when to run create pfile from spfile and the converse. Don't forget to consider what might happen in the future if you leave pfiles all over the place.

If the same stuff is in the pfile and spfile, it makes sense that the spfile has what the pfile would need.
