This asana builds stamina for 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 a 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.
