Are spells created or have they always existed but are being discovered?

Say I take someone’s ritual to ask a spirit for one thing, and modify it to ask the same spirit for something similar but not identical, is it the same spell, or a new spell in its own right?

A lot of advanced magical practices call upon the magician to be able to create his/her own rituals: although mostly this will be a case of building upon established principles in which he/she has been trained – e.g. the magical systems of the Golden Dawn or Thelema. Hence in that sense, although original magical rituals are continuously being created, very few rituals are “totally original.”

In the Abramelin system, it is theoretically possible to ask one’s HGA to reveal a new “spell” (i.e. a magick square or spirit, or both) if one doesn’t already exist to suit one’s purpose. Which is just as well, because if this were not so, Abramelin would not be suited to the 21st century but would be stuck in the 15th century. HOWEVER, I believe that the secrets the HGA reveals come from a place outside Time, so the question “is it new or does it already exist” cannot properly be answered.
