Modak, sweet balls, is one of the most important offerings made to Lord Ganesha. It is said that any offering to Ganesh is incomplete without the Modaks. There is an interesting story in the Padma Purana regarding why Ganesha loves Modak.
Once the Devas (demi gods) came to visit Shiva and Goddess Parvati and presented them a divine Modak. It was a very special Modak and the person who ate the modak will become knowledgeable in all scriptures, science, art and writing.
Goddess Parvati wanted to present it to her sons – Lord Ganesha and Lord Kartik. But the brothers were not ready to share it. So a confused Goddess Parvati said that who among you proves the true meaning of sincerity and devotion will get the Modak.
To prove the true meaning of devotion, Lord Kartik immediately mounted on his Vahana, or vehicle, and started visiting all the spiritual places.
But Lord Ganesha went around Lord Shiva and Goddess Parvati and said that no amount of offerings or fasting or visiting sacred places is equal to the devotion of one’s father and mother.
Impressed by Lord Ganesha’s explanation of true meaning of sincerity and devotion, Goddess Parvati gave the Modak to Lord Ganesha.
This is believed to be the reason for Lord Ganesha’s love for Modak.
