Suhas,
No disrespect, but is not what you say here, “wiser to go with it,” antithetical to yoga?
Yes, nature’s own system alternates the cycle, but its balance does NOT occur naturally (unless one is already a perfect specimen). It is restored and maintained through hatha/pranayama, and has more to do with resistance than volume: regulation and balance being effected by obstruction or size of the apertures.
Unfortunately, imbalance IS the norm, and that is proven everyday by what effectively becomes premature death. While most will “go with” this premature death, yoga suggests an alternative.
We are truly blessed to have freedom of balance in both nostrils, ask anyone with chronic congestion. When not, we must take steps to remove obstruction, open closure, purify, change diet, etc. It’s why we have a sutra neti, for example. It’s why we have yoga.
respectfully,
siva
