Yoshiro Tamura, "Introduction to the Lotus Sutra", p61-62Some contemporary Buddhist scholars view the Lotus Sutra as exclusive, contentious, and sometimes even combative. This can be regarded as another of the criticisms of the Lotus Sutra. Evidence for it being exclusive is found, for example, in the incident of the “departure of the five thousand” in the second chapter, in which five thousand people who did not understand the Buddha’s teaching got up from their seats and left, and the Buddha did not stop them but called them the dregs of the assembly. Such scholars regard all of the Mahayana sutras as negative toward the Small Vehicle to some extent, but none as extremely so as the Lotus Sutra.
They also suspect that the extreme practices of martyrdom and self-sacrifice found in chapter 13 are examples of something created by a distinct social group that was exclusive, closed, and estranged from the general society. From this they try to prove the exclusivity of the Lotus Sutra. And they relate to this what they see as the exclusivity and contentiousness of Nichiren or his followers.
There are additional criticisms, but we have discussed the main ones. The interesting thing is that there were also evaluations completely to the contrary. That is, there were those who praised the Lotus Sutra for establishing the supreme and absolute unifying truth (the Wonderful Dharma of One Vehicle), for elucidating the ultimate reality of this universe (the reality of all things), and for integrating various ideas. Just as the Lotus Sutra refers to itself as “great impartial wisdom,” followers of the Small Vehicle, who had been detested because they were never to become buddhas, are acknowledged by the Lotus Sutra as future buddhas under the unifying and integrating truth of the impartial one vehicle. In this respect the Lotus Sutra was seen as being the opposite of exclusive, namely inclusive and abundantly tolerant.
