Hi,
I am new here and this is my first post.
i believe in the karma thing and i am hesitating to perform this spell because i dont wanna manipulate anybody's free will
I wonder what free will has got to do with falling in love? Though they may decide later that it is a bad idea-rationally, the emotions elicited when love blooms are anything but. It is not wrong to want someone to love you. Even someone specific.
If you approach "casting a spell" in a scientific manner and simply record your results in your book there is no ulterior motive to karma, it is simply cause and effect. Whether you can live with the effects you cause is another matter. Most often I have found that people feel they don't deserve to be successful or rich or attractive and so when the opportunity arises they sabotage themselves so they can continue feeling the same way. I realize this is a general blanket statement so observe for yourself and see if it has the ring of truth. However to me, it is as if individually a person's "free will" isn't really free at all to begin with.
