Location
The seven weeks of meditation, which Goutama undertook to become Buddha, were dedicated at different locations and one such location is the Ratnaghara. It is believed that during one of the seven weeks, Lord Brahma and Lord Indra created a luxurious hall studded with seven precious elements for the Buddha to meditate. The Buddha was seen radiating lights of five colors through his meditating body and illuminate the nearby Bodhi tree.
However, the Chinese traveler Huen Tsang has described in his travel log that the precious elements had slowly changed into stone with passage of time immortal. Ratnaghara, today stands as a beautiful but lonely roofless shrine within the complex.
