The bodhisattvas described in the fifteenth chapter, “Appearance of Bodhisattvas from Underground,” who have sprung out of the great earth, as numerous as the number of dust-particles of 1,000 worlds, are followers of the Original Buddha Śākyamuni who resides within our minds.
They are like T’ai-kung-wang and Duke of Chou, retainers of King Wu of the Chou dynasty in ancient China, who at the same time served the King’s young son, King Ch’eng; or Takeuchi no Sukune of ancient Japan, a leading minister to Empress Jingu, who concurrently served her son, Prince Nintoku. Just like them Bodhisattvas Superior Practice (Jōgyō), Limitless Practice (Muhengyō), Pure Practice (Jōgyō), and Steadily Established Practice (Anryūgyō), the four leaders of these bodhisattvas sprung from the earth, are simultaneously followers of the Original Buddha and bodhisattvas who reside in the minds of us, ordinary people.
Therefore, Grand Master Miao-lê has declared in his Annotations on the Mo-ho chih-kuan (Mo-ho chih-kuan fu-hsing-chiian hungchiieh): “You should know that both our bodies and the land on which we live are a part of the 3,000 modes of existence which exist in our minds. Consequently, upon our attainment of Buddhahood, we are in complete agreement with the truth of ‘3,000 existences contained in one thought,’ and our single body and single thought permeate through all the worlds in the universe.”
