Lavaṇa rasa — salty
Softening / fluid-balance teaching proxy
Lavaṇa, the salty taste, is placed near a kidney and lower-abdominal proxy to evoke fluid and softening language used in teaching summaries. The locus is a target-organ projection of a taste property, not an anatomical salt reservoir or a clinical kidney assessment.
