The number of faces a bead can have varies from a single face up to 21 faces. They are used for different purposes, so it would be improper to just buy something in the shop and put it on the body. Wearing the wrong type could disturb one’s life. A lot of people want to wear an ek Mukhi, which has only one face because it is very powerful. You yourself have many faces. When you have many faces, if you wear an ek Mukhi, you are asking for trouble.
Five-faced beads or panchmukhi is safe and good for everyone – man, woman and child
People say if you wear an ek Mukhi, you will leave your family within twelve days. Whether you leave the family or not is not the issue, it is just that it will make your energies in such a way that you will want to be alone. It doesn’t make you compatible to be with other people. If you have to wear other kinds of special beads, it is best that it is received from someone who knows these things, not just buying from the shop and putting it on your system.
