Poorna Bhunjangasana or Full Cobra Pose aims to keep the spine supple and healthy. On a pranic level, this asana has a strong effect on all the organs related to swadhisthana, manipura, anahata and vishuddhi chakras.
Mayurasana is also known as the Peacock Pose. It counts as an advanced asana. It is very easy to fall forward in the final position and crush the nose on the floor. So be careful and, if necessary, place a small cushion on the floor under the face.
