Akashagarbha

Akashagarbha
[虚空蔵菩薩] (Skt; Jpn Kokuzo-bosatsu)

    The bodhisattva Space Treasury. A bodhisattva whose wisdom and good fortune are said to be as vast and boundless as the universe.
Ākāśagarbha Bodhisattva (Sanskrit: आकाशगर्भ बोधिसत्त्व; traditional Chinese: 虛空藏菩薩; pinyin: Xūkōngzàng Púsà; Korean: 허공장보살; Japanese: Kokūzō Bosatsu; Tibetan: Namkhai Nyingpo) is a Mahāyāna bodhisattva who is associated with the great element (mahābhūta) of space (ākāśa).

Ākāśagarbha is regarded 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 Esoteric Buddhism from Huiguo, and then go on to found the Shingon school in Japan.
