The OM symbol is an ancient symbol of Unity, Peace and Tranquility. OM is the sound of the infinite. If this sign is displayed on the outside of the main door of any House, Office, Business Premises or any other place then it is supposed to bring Good Luck, Peace and Prosperity for the people living or working inside the premises. The symbol Om is representative of Lord Ganesha who is also known as Vighnaharta which means Remover of all kinds of Obstacles. In Om, the upper arc is said to be the face of Lord Ganesha. The lower arc is his belly. The twisted arc which is on the right side of the Om is his trunk. Thus, Omkara represents the complete physical form of Lord Ganesha. Hence, this symbol provides a very auspicious positive energy at any place where it is displayed and any person who lives or works at such a place where a OM symbol is displayed is able to succeed by the blessings of Lord Ganesha.
