A sandstone slab with a group
that was found in
My Son (fig.)
from around the 10th to 11th century AD.
These type of stone
slabs with carved lingas could be moved about and placed in rivers,
in order to fertilize the water that flowed over it and
paddies so as to ensure an abundant yield.
the people of the past carved lingas into the riverbed
itself, as it was (and by some still is) believed that
any liquid, such as milk or water, passed over a linga becomes
sacred, even magical.
