Left Atrium Metaphorized (I): The Moon and its Rays

The left atrium is the moon.

Oxygenated blood is amrta / soma.

The pulmonary veins are the rays / parts (kala) of the moon.

The moon’s rays are the carrier of nectar (into the moon). Or, the moon is the receptacle of nectar.

The moon waxes as one moves towards the alveolar zone; the number of its rays increases. (There are 10 rays / kalas at the segmental level.)

The moon wanes as one moves from the alveolar region towards the left atrium.

The left atrium could be represented as “moon with no ray” (amavasya); then, at the alveolar level, we would have “moon with all its rays” (purnima).

As the moon’s rays increase / the moon waxes, the total amount (volume) of amrta does not increase; the same amount is distributed across the rays / parts.
