nāḍyaḥ —the veins;  asya —of the universal form;  nirabhidyanta —became manifested;  tābhyaḥ —from them;  lohitam —blood;  ābhṛtam —was produced;  nadyaḥ —the rivers;  tataḥ —from that;  samabhavan —appeared;  udaram —the stomach;  nirabhidyata —became manifested.
TRANSLATION
The veins of the universal body became manifested and thereafter the red corpuscles or blood. In their wake came the rivers (the deities presiding over the veins), and then appeared an abdomen.
PURPORT
Blood veins are compared to rivers; when the veins were manifested in the universal form, the rivers in the various planets were also manifested. The controlling deity of the rivers is also the controlling deity of the nervous system. In Āyur-vedic treatment, those who are suffering from the disease of nervous instability are recommended to take a bath by dipping into a flowing river.
