法華玄贊義決 1.122

1.122

謂聞聲執實謗無大乘者，據昔凡夫創聞小教執為究竟，謂無大乘。未曾聞說大乘，起謗此損減謗，遂依修小將為究竟，我究竟取如是涅槃。今聞大乘既信不謗，但揣無分不能進修，既聞唯一，便謂無有聲聞得滅，返道疑生故名為損。故下文云：若我弟子實得阿羅漢辟支佛，不信是經無有是處。

Saying that 'they hear the sound, cling to it as real, and slander, claiming there is no Mahāyāna' is based on the ordinary persons of the past who, upon first hearing the small teaching, clung to it as ultimate, claiming there is no Mahāyāna. Having never heard the Mahāyāna expounded, they gave rise to slander; this is the slander of diminution. Thereupon, relying on cultivating the small, they took it to be ultimate: 'I shall ultimately attain such nirvāṇa.' Now, hearing the Mahāyāna, they believe and do not slander, but merely assess that they have no share in it and cannot advance in cultivation. Since they hear that there is only one [vehicle], they then suppose that no śrāvakas attain extinction, and turning away from the path, doubts arise; therefore it is named diminution. Hence a subsequent passage states: 'If there are disciples of mine who have truly attained the status of arhat or pratyekabuddha, that they should not believe this sūtra is impossible.'
