The Ratanaghara or the Jewel House is the place where the Buddha spent the fourth week in meditation. Situated in the north-west of the Temple, the Buddha meditated here reflecting on the Patthana or the Law of Dependent Origination. A ray of six colours was said to have emanated from his body during that period and the Buddhists have designed their flag based on these colours.
