Many sūtras other than the Lotus preach variously according to the caliber of listeners. For instance the “five precepts” are preached for those in the human realm, the “ten good acts” for those in the realm of heaven, compassion and charity for the King of the Brahma Heaven, equal alms-giving among priests for the king of devils, 250 precepts for monks, 500 precepts for nuns, the four noble truths for men of śrāvaka, the 12 links of cause and effect for men of pratyekabuddha, and the six pāramitā for bodhisattvas. It is like water taking its shape according to the container or an elephant exerting its strength according to the enemy.

This is not the case with the Lotus Sūtra, in which the same Lotus Sūtra is preached for all the eight kinds of protectors of the Lotus Sūtra and four kinds of devotees. It is as if a ruler straightening a curved line or a lion exerting his full power regardless of the strength of its prey.
