ā kā śa ga rbha
Ākāśagarbha (Japanese: 虚 空 蔵 = kokūzō) is an important figure in far eastern Buddhism. His emblems are the sword and cintamani (or wish fulling jewel). He is sometimes shown as here, and sometimes with his right hand in the varada, or giving, mudra. He is one of the eight Great Bodhisattvas.
Ākāśagarbha is very important in the life story of Kūkai. As a teenager he met a Buddhist priest who taught him a mantra of Ākāśagarbha known in Japanese as Gumonji-hō, also known as the Morning Star Mantra (see below). It was in repeating this mantra millions of times that he had some decisive spiritual experiences, including many powerful visions of Ākāśagarbha.
Seed Syllable
The seed syllable of Ākāśagarbha is trāḥ, which is also associated with Ratnasambhava in some mandalas.

Repeated one million times according to the requisite rituals, in a certain time period, one gains the ability to remember and understand any text.
