It is clear that Nichiren was no longer advocating even the Mahāyāna precepts of the Brahmā’s Net Sūtra. He believed that the practice of revering the true spirit of the Lotus Sūtra by invoking its title transcended any precept codes or particular Buddhist practices or lifestyles inherited from the past as those were all just provisional methods based on provisional teachings that were no longer efficacious. The following statements of his in other writings also express his view that faith in the Lotus Sūtra is what leads to buddhahood and not the observance of precepts:

Speaking of Ajātaśatru and Devadatta: “I am convinced that ordinary people in the Latter Age of Degeneration commit sins more or less. Whether or not such a man can reach Buddhahood depends not on how serious his sin is but whether or not he believes in the Lotus Sūtra. (Hori 2002, p. 188)

It is preached in the Lotus Sūtra, the “Appearance of the Stūpa of Treasures” chapter, ‘Upholding this sūtra is what is called observing the precepts.’ (Hori 2004, p. 214)
