In the Bosnian rituals of black magic another powerful way of destroying your enemies is known using živa or mercury (quicksilver or hydrargyrum) which can be found in Romania and Bulgaria. The belief in the magical power of mercury stretches all the way to Iran where mercury was prepared in a special way. The word mercury comes from the Persian verb "Ji" which means to live and it is also used by the Arabs and South Slavs.
When someone wants to get revenge on his enemy and place the burden of disease or some other evil onto him, he needs to get a hold of some mercury that he then carries to the Imam who will utter specific prayers and curses onto it. When the mercury is processed in such a way, it is then ready for usage. At midnight the person that will send the mercury (živa) will suddenly tale off his or her clothes and walk outside into the yard, and take some dirt or dung and places it into his/her mouth. Then the one needs to stand on one leg and utter: "I am a Jinn, I am standing on one leg..." Then the drop of mercury is placed on the ground and apparently the drop will head in the direction of the person whose name was uttered.
According to the beliefs, živa moves only during the night while it stands still during the day. While it may take several days for the mercury to reach its victim, it will not be stopped in its intent. If the victim spots the mercury shining in the dark of his/her room the person can save himself/herself by peeing on the mercury, that way the mercury loses all of its power. However if the person swallows the mercury it will suddenly fall ill and in a very short period die if he is not helped.
