“AN IT HARM NONE, DO WHAT YE WILL.”
The Wiccan Rede basically means – live and practice magick however you want as long as you cause no harm to anyone. This is why most spells and rituals will include word such as “harmeth none” or “for the highest good of all” to explicitly send good intentions only.
Magick (energy) is neither good or bad, white or black, it is the intention the person sends that causes a positive or negative outcome. Keeping positive and in high vibrations is important when performing rituals and spellwork.
Similar to the law of Karma, the Threefold Law is that any magick we send out will come back to us three times as powerful (threefold). Therefore if what you are casting is positive and with good loving intentions you should receive that energy back threefold. On the flip side if what you send out is of bad intentions then what comes back to you will be three times worse (like attracts like).
It is unethical and against the law of Free Will to perform any spell on another person without their knowledge or permission. This would be extremely bad karma and should absolutely be avoided.
For example, you cannot cast a spell to make someone fall in love with you. This is against the other person’s free will.
However, you could cast attraction or self empowerment spells/rituals to hopefully attract the right person to you and to give out the confident energy to attract the type of person you want in your life.
