How is it done?

First step is to be very close to your target. The goal is to be standing in their aura. Eye is useful paired with a hypnotic look as this can stun a person for a moment. Next, you can incorporate physical . As an example a hand shake or a hand on the shoulder can help to send a signal to the person. With all of the steps together you have made a link. Make sure to use your willpower and mind to command that person, speak to this person with a soft voice or monotone tone, whispering in the ear is useful. You can use this for getting some information out of a person, to get a person to forget what he saw, and of course to feed on someone.
