The Memorial Stone of Time

As you arrive you see a rather old memorial stone and a pot. Try to resolve the mystery based on the text engraved on the memorial stone.

"Azunak created life and the heavens,
and we lift up our crops in response to his creation.
The one with the countless shiny teeth shall be put inside
and there will be joy.
A sturdy rock shall be
included, and we shall give thanks.
There will also be a soft crane feather and
there shall be blessings."
