What is Marichyasana 3?
Unlike Marichyasana I and II, Marichyasana III is not a forward bend, rather a deeper seated twist. It is often included following a seated forward bend sequence. It is useful, initially, to take height under the bottocks to allow the arm to wrap around and clasp the back hand. The initial focus is simply the twisting action which must commence low in the abdomen so as to enable the front shoulder to move beyond the thigh.
