Ākāśagarbha Bodhisattva (Sanskrit: Chinese: 虛空藏菩薩; pinyin: Xūkōngzàng Púsà; Japanese pronunciation: Kokūzō Bosatsu; Korean: 허공장보살; romaja: Heogongjang Bosal, Standard Tibetan Namkha'i Nyingpo, Tibetan: ནམ་མཁའི་སྙིང་པོ།) is a bodhisattva who is associated with the great element (mahābhūta) of space (ākāśa).
Ākāśagarbha is regarded[who?] as one of the eight great bodhisattvas. His name can be translated as "boundless space treasury" or "void store" as his wisdom is said to be boundless as space itself. He is sometimes known as the twin brother of the "earth store" bodhisattva Kṣitigarbha, and is even briefly mentioned in the Kṣitigarbha Bodhisattva Pūrvapraṇidhāna Sūtra.
Kūkai, the founder of Shingon Buddhism, met a famous monk who is said to have repeatedly chanted a mantra of Ākāśagarbha as a young Buddhist acolyte. Kūkai took a tutorial with him on Kokuzou-Gumonji (a secret doctorine method, 虚空蔵求聞持法). As he chanted the mantra, he experienced a vision whereby Ākāśagarbha told him to go to China to seek understanding of the Mahāvairocana Abhisaṃbodhi Sūtra. Later he would go to China to learn Tangmi from Huiguo, and then go on to found the Shingon in Japan.
Two Mahayana sutras are known to survive in which Ākāśagarbha Bodhisattva is a central figure:
- 《虛空藏菩薩經》 (Ākāśagarbha Bodhisattva Sūtra)
- 《虛空藏菩薩神咒經》 (Ākāśagarbha Bodhisattva Dhāraṇī Sūtra)
The mantra of Ākāśagarbha is popularly used by Shingon Buddhists, practitioners of Tangmi, and by artists. It is believed to give rise to wisdom and creativity, and dispel ignorance.
