if I cast a love/sex spell on someone whenever the waning comes shouldn't I cast an obsession spell during waning upon the same person or will that backfire
Why the hell would you cast an obsession spell on the person you're trying to fall in love with you? That will end very ugly, especially if it backfires! You are warned.
For growth, cast a spell during a waxing moon.
For loss, cast a spell during a waning moon.
Read more about spell workings on JoS, it is very good explained. Make sure to read everything.
Taol is completely right! I know this because I was completely obsessed with another person once. I lost myself so to speak for a while. It ended very ugly. And I owe Satan and my guardian so much for helping me out. The meditations helped.
I speak for everyone here, do NOT do this.
FYI, it happened to me because of a Pluto/venus contact/transit.
