Legend has it that Lord Shiva once visited
Anusuya in the forest. He was seated for a
meal next to a young Ganapati.
Lord Shiva was famished and asked to be served
food immediately. Anusuya, however,
said That she would serve Lord Shiva only once
Ganpati's hunger had been satiated.
Ganpati, a
voracious eater, happily ate all that was served
to him but his hunger was insatiable. Even his
mother, Goddess Parvati was astonished at
the sight of her young son's insatiable
hunger.
Realizing that Lord Shiva would
remain hungry due to Ganpati's hunger,
Anusuya served him a single piece of
sweetened food. Upon consuming this,
Ganpati gave a loud burp, hence indicating that
his stomach was finally full.
Goddess Parvati
was curious to know what the sweetened food
item was that Anusuya had served Bal Ganesha.
On learning that it was a modak, Goddess Parvati
expressed her wish that devotees of
Lord Ganpati should always offer modaks to
him and this wish has since been granted
across generations and location
