Yoga danda

This is a yoga-danda. Yoga-danda litterally means "yogic stick" but specifically refers to this instrument which can be used to change nostil dominace. The Western research on nostil dominance seems to have mixed results (which I am certain can be resolved by looking at the research methodology critically). In general, nostril dominance is associated with various physical, mental, emotional states within yogic traditions. I am confident these will mostly be proved accurate in carefully controled research. Simply put, press the yoga-danda into the left armpit, and the right nostril will open more... And visa-vesa. A truly simple life-hack.
