"Jizo stands for the mind-nature of ordinary people. Ji (the character for earth) is the foundation of the mind. Zo (the character for storehouse) is the storehouse of Buddha nature. It is in this Buddha nature that all the virtue of ordinary people is contained. Hence it is called the storehouse of the Tathagata. When the mind is deluded, as many ignorant thoughts as sands of the Ganges arise; when enlightened, this mind gives birth to infinite wonderful meanings. Being the source of good and evil, this mind is called earth (Ji). The earth gives birth to trees and grasses, hence it is used as an exemple here. Nature, the place where all the jeweled Dharmas return, is referred to as the storehouse (zo). That is why Jizo (earth-storehouse) is another name for mind-nature. Originally mind and nature were not separate. They were the one center where ordinary people in the six realms observed and perceived, and where they were masters of the six senses. It is here that they were teachers of those in the six realms. Since the four activities (walking, standing, sitting, and lying) of Buddhas and ordinary people throughout the day and night are the wonderful work of this mind-nature, it is referred to in the sutra as 'each day'. As for 'early morning', it refers to the period before the distinction between black and white. Early morning means original nature - where there is no division between Buddhas and ordinary people."
