Marichasana C is a spinal extension that uses space created between the vertebrae to twist and bend. If you fail to create this space then the posture will not achieve its maximum benefit. Some benefits that come from creating space between vertebrae include increased flexibility in the spine, healthy posture, good digestion, decreased lower back pain and most importantly the slow rise of life energy or prana along the central column of the body. Lifting the spine up out of the pelvis is only possible when you carefully and consciously apply the tools of breath and bandha to connect with the core muscles of the body. One you have established this as the foundation you can then keep both sitting bones grounded with the careful application of the pelvic floor muscles, known as mula bandha. The sitting bones will remain on the same plane and the pelvis will not twist to the right or left as it is your foundation and link to the ground. As you lift your spine up and out of the pelvis try tipping your weight slightly towards the front of your sitting bones. Be careful here not to arch too far forward into a backbend because the purpose of tipping the weight slightly forward is just to prevent leaning too far back and to letting the lower back round. It is very important that you keep the weight forward and the hip joint that you are twisting around flexed or bent deeply to protect the lower back during this twist. Once you have established the breath-bandha connection along with a solid foundation through the pelvis, exhale as you twist towards your leg, deepening the hip crease. Initiate the twist all the way from the core of the pelvis and lean over from the side to get the whole torso, chest, mid-section and stomach wrapped as deeply around your thigh as possible.
Twisting in this manner helps open the back muscles, stretching key areas that often get tight from lack of mobility. When the body is immobile over long period of time muscles, fascia and other tissues often build up like a protective armor. This twisting posture is an easy way to access some of the cleansing benefits of the Ashtanga Yoga method. Do not be surprised is some emotions surface after you dig through some of the most tight and stuck areas of your body. Furthermore sucking the belly in while twisting literally wrings out the digestive track and help push through any old accumulated toxins or other materials from the system. Purification of the digestive track is a key cleansing aspect of the Ashtanga Yoga method. With a healthy digestion the body of the longterm yoga practitioner is healthier and more free. Once the proper technique is established and the body has been sufficiently cleansed the twist itself will be light and easy.
The last and often overlooked portion of Marichasana C is the shoulder girdle. This area must also participate in the twist. The emotional and psychological body are often tested from deep movement in the shoulders as the shoulders themelves form the gateway to the heart. In Marichasana C there is also a twist in the shoulders as the arm that binds around the forward thigh must tip forward and down around the shin of the bent leg, while the hand that reaches around the back must rotate in the opposite direction. In essence there is a second twist along the shoulder girdle that is needed for the full expression of the posture. Many people lift their spine only along the center line and thereby twist themselves off of the bind around the leg. Pay careful attention to keep the body close to the thigh that you bind around and avoid the temptation to just reach with shoulders. Instead twist from deep within the body, lean the body weight around the bend knee and rotating the shoulders to reach the arms. Grabbing your hands is really a secondary movement that finishes off the twist along the shoulder girdle. Placing too much emphasis on grabbing the wrist or any other goal might damage your ability to feel the subtlety of the posture. Be conscious and patient and remember to feel the inner body.
The benefits of this simple twisting posture is available for everyone. You do not need to be young or flexible to experience the powerful effects of Marichasana C. As my teacher, Sri K. Pattabhi Jois said and as it states clearly in the Hatha Yoga Pradipika, yoga is for everyone of all ages, genders, sizes and shapes. The same principles developed in a relatively simple twist like Marichasana C can be applied to much more complex twisting motions that come in more advanced Ashtanga Series. However, the key alignment pointers and subtle principles must be established from the beginning in order to assure a practice with the perfect mix of strength and grace.
