Atharva Veda 1.17

To stop the vessels of the body

Yon women (yoṣít) that go, veins with red garments, like brotherless sisters (jāmí)—let them stop (sthā), with their splendor smitten.

Stop, lower one! stop, upper one! do thou too stop, midmost one! if the smallest stops, shall stop forsooth the great tube (dhamáni).

Of the hundred tubes, of the thousand veins, have stopped forsooth these midmost ones; the ends have rested (ram) together.

About you hath gone (kram) a great gravelly sandbank (dhanū́); stop [and] be quiet, I pray (sú kam).
