Lord Ganesh is one of the best-known and most widely worshipped deities in the Hindu pantheon. Ganesha is widely revered as the Remover of Obstacles and more generally as Lord of Beginnings and Lord of Obstacles (Vighnesha, Vighneshvara), patron of arts and sciences, and the deva of intellect and wisdom. He is honored at the beginning of rituals and ceremonies and invoked as Patron of Letters during writing sessions.
This Ganesha Idol was established by the trinities (of hinduism) such as Bhrama-God of Creation, Vishnu-God of Protection, and Shiva-God of destruction in Satya Yuga to destroy the demon TRIPURASURA. Yuga is the name of an 'epoch' or 'era' within a cycle of four ages. These are the Satya Yuga (or Krita Yuga), the Treta Yuga, the Dvapara Yuga and finally the Kali Yuga. We are in Kali yuga. Tripurasura was an asura(demon) who tormented people, saints , sages demigods, gods in Krita or Satya yoga. He who inhabited Tripura, a mythological triplet fortress made of iron, silver and gold constructed by Mayasura. From a boon he had grown very powerful and gods could not destroy him. However his end would come from a bachelor who enters wedlock, yet lives a salebacy life! All the gods came together formed shakthis known as Siddhi and Buddhi as Lord Ganesha's brides. Lord Ganesh married both Sakthi and buddhi in the presence of all, and later the shakthis turned in to his weapons. Lord Ganesha holds these weapons in hands, always. Meanwhile Tripurasura roams freely causing all the mayhem and chaos around the world. His end is by this Lord Ganesh in Kaliyuga!
