The Buddha's head hangs over his chest.

The end of the rosary, the knot, is called the Buddha's head.

When wearing beads, the head of the Buddha should be behind the neck, opposite to the chest.

So even if you don't touch the pendant, it's a standard way to leak beads.

Buddha ornaments, such as rosary beads or small Buddha statues, must always be placed too far on the incense burner to be clean. Otherwise, the wearing effect is very weak.

Of course, chanting, holding spells, chanting and blessing Buddha are better.
