This is not recommended even for the most advanced magicians because there are safer ways to bring spirits into your life that won’t cause such a huge energetic shift leading to chaos. However, you can technically do this when you have sex with someone in a penetrative position either as the receiving or giving party. Note that this spell is only about stealing spirits, it’s not about handling the consequences of stealing spirits because that depends on which magician or person you take the spirits of. I would also like to note the average non-spiritual person usually does not have the best entities attached to them and the spiritual person won’t appreciate you taking their energies from them. I am only sharing this because of its folkloric value and because you may want to realize or know when someone is attempting to do it to you.
While in an intimate position with the other person, use your aura to pull into itself energy from your partner. During copulation your energies are connected, and you can drain them in multiple ways but this is baneful and there are other non-destructive ways to achieve spiritual gain. For the purpose of stealing spirits, energetically drain the outside of their aura where attached spirits would stay. You know you have succeeded when your aura feels imbalanced or you feel yourself adapting to the new energies. The other person may say they feel drained or suffer from post-coital depression, but they can fully recover after just a few days without any intervention from spirits or spiritual practice. A magician who realizes they have been drained can recover in a few hours or even one hour with certain resources or rituals.
People with toxic personalities or who are draining such as teachers or employers who take up excessive time with work or friends who take up excessive energy with drama will naturally drain you during sex (Just like any interaction) but they won’t be able to take spirits without intention and knowledge, and even if they somehow did it would ruin them since they do not have the tools to live with them.
