The word myō means gusoku (to be equipped with perfect teaching); “six” means all kinds of practices collectively designated as six pāramitā or six kinds of practices required for the attainment of Buddhahood. Śāripūtra and others wished to know the way in which a bodhisattva could fulfill the six pāramitā in order to obtain Buddhahood. Gu in gusoku means “mutually-possessed characteristics of the Ten Realms, and soku means to be satisfactory, that is to say, it is satisfactory for each of the Ten Realms to contain in itself characteristics of the other Nine Realms. Altogether of the 69,384 characters of the Lotus Sūtra, in the twenty-eight chapters in eight fascicles, each contains the character myō; each of them represents the Buddha with thirty-two or eighty marks of physical excellence. As each of the Ten Realms contains in it characteristics of the realm of the Buddha, Grand Master Miao-lê states in his Annotations on the Great Concentration and Insight, “Each realm contains characteristics of the realm of the Buddha, not to speak of those of the other Nine Realms.”

In response to the request by Śāripūtra and others to know how to fulfill the six pāramitā, Śākyamuni Buddha declares in the second “Expedients” chapter of the Lotus Sūtra that all Buddhas hope to open the gate to the wisdom of the Buddha for the people. The people here refer to the men of the Two Vehicles such as Śāripūtra, who had been considered unable to obtain Buddhahood, men of icchantika lacking the Buddha-nature and all those in the Nine Realms (except the realm of the Buddha). Therefore, His vow to save all the numerous people was at last fulfilled in preaching the Lotus Sūtra. That is what He meant in declaring in the same second chapter of the Lotus Sūtra: “I had vowed to make everyone exactly like Myself. The original vow of Mine has already been fulfilled.”
