anything you do comes back u know. your basically asking the universe to pay attention to you individually, your life and plight so to speak. we as humans cant control what they see. IE, you could mean for them to only see the part where someone wronged you, but the entity sees 360 degrees, and they also see whatever you may have done to deserve the slight. and we certainly cant control the entity's thought process to determine what they feel you deserve in return for asking a boon of them, if that makes sense. so if you ask for happiness on another, you will get positive in return and vice versa. to say you are a 100% victim to us in 1 thing, nut you cant lie to the higher power. its all knowing. not trying to sound like a know it all, im only giving you advice to really think about what your planning on doing before you do something that could alter your life in a devastating way. plus, for death of any kind, you going to need more magical based tools, gems, and devices of power than just a simple candle. they are used as well as incence and herbs in most spells but taking away life from anything takes huge power if you are planning on using magic to do it. if it was easy we would have a lot more magic users and less murders and psycopaths lol. there is a fine line between the two ya know.by doing that your basically saying that you have the right credentials to determine if this other life deserves to breath or live. if you dont believe that, then your simply saying that because you feel obliged, this life needs to be extinguished. not saying your right or not, just saying its a serious thing that you should think about it. sorry if i offended you, i only wanted to help you. ( im a reeeaalllyy bad speller on computer. i cant look and type lol sry.)
take a black candle, and focus all your energy into the candle. if you want to say a chant you can, then light the candle and visualize your intent. candle magic is really simple, as long as you can visualize and focus energy, they will work. as you advance in candle magic, you can add herbs, oils, runes, and many other things to the spell, but the basics remain the same, focus your energy into the candle, and visualize your intent.
if you're trying to curse someone, carve their name, or melt the wax over a picture of the person. be sure to cast it during the waning moon phase [full-new] since it's the best time to cast these types of spells.
