Akashagarbha Bodhisattva ( Sanskrit : आकाशगर्भ बोधिसत्त्व, Ākāśagarbha bodhisattva , Chinese 虛空 藏 菩薩 , Pinyin Xū kōng zàng pú sà , Japanese 虚空 蔵 菩薩 , Kokūzō bosatsu , tib . : ནམ་མཁའི་ སྙིང་ པོ ། , nam mkha'i snying ), in English " Bodhisattva of space", so called because his wisdom and happiness reach as far as the infinity of the universe, is a central figure in Shingon Buddhism as well as Nichiren Buddhism and one of the eight great Bodhisattvas of Mahayana -Buddhism. He is also known as the twin brother of the Bodhisattva Ksitigarbha and is often depicted with a crown studded with diamonds that represent the five wisdoms. In his right hand he holds the sword of justice, in his left hand a lotus flower and a precious stone. The lotus flower in this case stands for good circumstances and the gemstone for the fulfillment of wishes.
