Answer:
The most common rules of witchcraft are that whatever you send out, comes back threefold to you, so if you bind someone, against their will, you may be forced to do 3 things against your will.
It is highly not recommended to do any type of spell against someone's will.
The best and most effective way to do any love spell is to do a generic love spell in which your true love will find you. It may not be the person you originally hoped for, but it will be the way destiny has decreed.
A Pagan Perspective
First, to answer your specific question; yes, binding spells, including binding love spells do work.
Second, as stated above there are a few things to consider before you undertake this sort of thing.
- Are you sure you know what you are doing?
A binding spell removes the option of free will from the one being bound. This is the magical equivalent of kidnapping and forcible confinement (If there is sex involved it is magical rape). Are you sure you want that responsibility and negative karma on your soul? If you still want to go ahead with this spell, do you have ALL of the necessary research done, materials gathered, times figured to the minute, and spell written down? Do NOT use a pre-made, found in a book somewhere spell, if you are serious about this you must do the "homework" yourself.
-What are your true motivations?
Is this a spell you are planning to draw someone that does not feel attracted to you? If so, see above concerning kidnapping, forcible confinement and rape.
Is it for someone (a celebrity) you do not know? If so, see above and think carefully about what you are planning, nice as it might seem just now, binding yourself to someone you do not know well is just plain foolish.
Is this designed to bind you and your girl/boy friend together for eternity because you really think you love one another? The binding of two souls for that long is really not advisable as people change, not just the other person, but you as well. The things you "love" right now will be of less importance in the future and being bound to someone is a far reaching thing.
Is this designed to be part of a handfasting or marriage ceremony? If so, then take a good look at the wording of most such ceremonies. Handfastings are worded "As long as the love shall last." and Christian marriages are worded "Till death do us part." Do you really want to bind yourself to someone for eternity?
- Could this be harmful to anyone? The "Threefold Rule" generally governing the use of magics states "That which you send out will return to you threefold." If you hurt someone else, you will be subject to three times the harm in your own life.
- What will you do when you change your mind? Reversing or breaking a binding spell is extremely difficult, time consuming, and takes an awful lot of your personal power to do it. And you will have to do it or you will leave a wounded soul alone for eternity and at the same time your own soul will be equally bound to that damaged soul.
