...GANESH PUJA...

Ganesha Chaturthi (गणेश चतुर्थी) is the Hindu festival celebrated in honour of the god Ganesha, the elephant-headed, remover of obstacles and the god of beginnings and wisdom. The festival, also known as Vinayaka Chaturthi, is observed in the Hindu calendar month of Bhaadrapada, starting on the shukla chaturthi (fourth day of the waxing moon period). The date usually falls between 19 August and 20 September. The festival lasts for 10 days, ending on Anant Chaturdashi (fourteenth day of the waxing moon period).
The festival involves installing clay images of Ganesha in public pandals (temporary shrines), which are worshipped for ten days with different variety of herbal leaves, plants and immersed at the end of the festival in a water(lake) along with the Idol. After adding herbal and medicated plants and leaves(patri) in lakes, the water in the lake becomes purified. This was in practice because, in early days people used to drink lake water, and to protect people with infections and viral diseases especially in this season, this tradition was introduced. Some Hindus also install the clay images of Ganesha in their homes. It is believed that Ganesha bestows his presence on earth for all his devotees during this festival. The festival is celebrated as a public event since the days of Shivaji (1630–1680).
While celebrated all over India, it is most elaborate in Maharashtra and other parts of Western and Southern India. Outside India, it is celebrated widely in Nepal and by Hindus in the United States, Canada, Mauritius,[3] Singapore, Indonesia, Malaysia, Thailand, Cambodia, Burma, Fiji, Trinidad & Tobago, and Guyana.
Celebration, Rituals and Tradition
Weeks or even months before Ganesh Chaturthi, artistic clay models of Lord Ganesha are made for sale by specially skilled artisans. They are beautifully decorated and depict Lord Ganesh in vivid poses. The size of these statues may vary from 3/4 of an inch to over 70 feet. The tallest Ganesha Idol made which stood 117 feet tall was situated in the city of Visakhapatnam in 2012.
Ganesh Chaturthi starts with the installation of these Ganesh statues in colorfully decorated homes and specially erected temporary structures mandapas (pandals) in every locality. The pandals are erected by the people or a specific society or locality or group by collecting monetary contributions. The pandals are decorated specially for the festival, either by using decorative items like flower garlands, lights, etc. or are theme based decorations, which depict religious themes or current events.
The priest, usually clad in red or white dhoti and uttariyam (Shawl), then with the chanting of mantras invokes the presence of Ganesha using the statue as a channel, or body for his energy. This ritual is the Pranapratishhtha. After this the ritual called as Shhodashopachara (16 ways of paying tribute) follows. Coconut, jaggery, modaks, durva (trefoil) blades of grass and red flowers are offered. The statue is anointed with red unguent, typically made of kumkum and sandalwood paste. Throughout the ceremony, Vedic hymns from the Rig Veda, the Ganapati Atharva Shirsha Upanishad, and the Ganesha stotra from the Narada Purana are chanted. There are certain methods on how to celebrate the festival including how to perform the Ganpati Staphna (Idol Installation), perform the Ganesh Visarjan (Immersion) and other rituals and traditions which should make a part of your festivity.
