The Lord Ganesha on a mouse represents the form of “Vijaya Ganapati,” which is a symbol of victory in overcoming darkness and all obstacles. The mouse (Musika) is his vehicle and companion, acting as a medium to receive prayers from humans and deliver them to Lord Ganesha. Worshiping this form is often believed to bring success in careers, finances, and the power to govern and manage subordinates.
Lord Ganesha, the great deity of Hinduism, is the god of success and fulfillment of desires, the god of arts and all sciences. He is revered not only by followers of Hinduism but also by many Buddhists, who honor and worship Lord Ganesha in large numbers.
