चक्रासन / Chakrāsana
Chakrasana (cha-KRUH-suh-nuh) benefits the nervous, digestive, respiratory and glandular systems, stretching the inner organs fully. It also strengthens the spine, thighs and buttock muscles, while increasing flexibility of the hips. This pose also brings blood to the brain, therefore nourishing it. It is a good pose to remove sluggishness of the body and builds stamina.
This asana builds stamina for the practice and removes dullness from our body and mind. Sage Patanjali in the Yoga Sutras says “sa tu dīrgha kāla nairantarya satkārā sevito dṛḍhabhūmiḥ” This means that practice becomes firmly grounded when well attended to for a long time, without break and with deep devotion to that which is real. The practice of yoga should not be interrupted by our likes and dislikes. One should practice with the right attitude as mentioned by Sage Patanjali. Therefore to maintain an interruption-free practice one needs to have stamina and strength in the body and mind.
Those with high blood pressure, glaucoma and detached retina should avoid this pose. If the wrist is weak try doing this pose from a chair to remove the weight of the body from the wrist. If there is any disc compression avoid this pose. Also avoid this pose in the later stage of pregnancy. Women who are menstruating can do this pose from a chair, which will be less exerting.
