To worship Ganapati, you should clean the home, place the idol on a clean platform, and offer water, flowers (especially red), incense, and sweets like modak or laddoo. Light a ghee lamp and camphor, then recite mantras such as "Om Gam Ganapataye Namaha" to seek blessings for guidance, strength, and prosperity. A ritualistic practice called pulling the ears involves gently pulling your earlobes to express humility and submission to the deity.
