Buddhism was founded by Gautam Buddha around 2500 year ago. Thereafter Buddhism was spread allover India and also outside India. Buddha did not believe in image worshiping. He never supported the existence of god, He advised people that they should be their torch-bearer and surrender to themselves. Consequently ‘Image’ had no place at the time of rise of Buddisim. The image of Buddha comes into reality around six hundred years after the foundation of Buddhism. During the period various symbols were being searched out for Buddha i.e Buddha's footprints, Bodhi-tree, Lotus Flower, tree, Riderless horse, An empty throne, Stupa, etc. Rajgrah, Vaishali, Kapilvastu, and Kushinagar are places where the important events of the life of Buddha had taken place. Emperor Ashoka had contracted main stupa of Sanchi.
Stupa was contracted with specific objects which can be described as to preserve the remains of Lord Buddha and his followers, to show the respect for statue of Buddha earlier to Gautam Buddha, to highlight, worship, the places where the important events of life of Lord Buddha had taken place. Some utilized things by Buddha were placed in stupa. Accordingly stupa is described as A. Physical stupa, B. Stupa having things utilized by Buddha C. Objective stupa.
Stupa was constructed with the object to spread the message of Gautam Buddha in public.
