Rasa dhātu — nutritive fluid proxy

First tissue / circulating nourishment

Rasa dhātu is rendered as the first nourishment of the seven-tissue sequence, using the chest and heart region as a visual proxy for circulation and nourishment. This is a target-organ projection of a substance classification, not an anatomical map of plasma or a claim about a fixed rasa location.
