I agree with the advice given on love spells. My fiance and I use them all the time -- but with the other person's full permission. We've bound ourselves to each other at the same time and did love spells that strengthen each other's ability to feel the other's love energy. But always -- and I repeat always -- with consent. I'm the Witch amongst the two of us, but at times I think he's worse than me! He casts love spells like they're to be eaten.
That being said, we don't take away each other's free will. We cast the spells with full knowledge that this is what we both desire and no one is being forced into anything. Consent and free will are my points here.
Also, why are you casting that love spell? Do you truly love the said person, or is it merely an experiement? Is the person going to be used as a means to an end? I believe that Love Itself is a spell, so you don't need to brew up anything. Just be yourself and love with every fibre of your being. If the person is meant for you he/she will return the love. But binding him/her via a love spell without their permission and/or knowledge thereof is Philosophically/ethically incorrect. Wrong. Taboo.
Things will not last. There are always conequences for taking away the other person's free will. My mentor tought me this from day one. So I would say think this through very carefully and analyze all the angles before deciding whether or not to cast the spell. Have peace about your decision in knowing that you are harming no one -- including yourself.
Blessed be )O(
