Indra's Net. A vast net that hangs in Indra's palace in which the strands are joined together by jewels. When light reflects onto one of the jewels， the same light is reflected and re-reflected endlessly throughout the expanse of the net. This is a metaphor used in Huayan 华严 Buddhism， taken from the Huayan jing， to express the concept of mutual interpenetration. Also written in Chinese as 帝释网 and 帝网.
