It is the Sūtra of Infinite Meaning alone which disparages the sūtras preached during the pre-Lotus period of 40 years or so and lauds just one sūtra, the Lotus Sūtra. It declares that the truth is revealed not in those sūtras expounded in the past 40 years or so, nor in the Sūtra of Infinite Meaning, which is now being preached, or in the Nirvana Sūtra, which is to be preached, but in the Lotus Sūtra alone. Śākyamuni Buddha as well as all Buddhas in the past, present and future appear in the world preaching all the scriptures of Buddhism. They all consider the Lotus Sūtra supreme. Social status, for instance, varies according to the time and circumstance. In the countryside farmers and retainers call warriors “upper class men,” but in the capital region warriors of the Minamoto and Taira clans are men servants while “upper class men” are applied to the members of the three aristocratic families. Again, if masters are called kings, even a farmer is the king of a family whereas the stewards and proprietors of shōen (manor in Medieval Japan) are kings of respective villages, districts, counties and provinces. However, none of these is the great king.
