In one method, the mala is hanging between the thumb and the ring (third) finger. The middle (second) finger is used to rotate the mala by one bead towards oneself with each repetition of the mantra.
In the other method, the mala is hanging on the middle finger, with the thumb used to rotate the mala just as explained - one bead at a time.
Either way, the index finger is never used to touch the mala.
