無量壽經優婆提舍願生偈註 1.46

1.46

此四句名莊嚴大義門功德成就。門者，通大義之門也。大義者，大乘所以也。如人造城，得門則入。若人得生安樂者，是則成就大乘之門也。佛本何故興此願？見有國土，雖有佛如來賢聖等眾，由國濁故分一說三，或以拓（聽各反）眉致誚、或緣指語招譏。是故願言：使我國土皆是大乘一味、平等一味，根敗種子畢竟不生，女人殘缺名字亦斷。是故言大乘善根界，等無譏嫌名，女人及根缺，二乘種不生。

These four lines are called the accomplishment of the adornment of the merits of the gate of great meaning. "Gate" means the gate providing access to the great meaning. "Great meaning" refers to the purpose of the Mahāyāna. Just as when a person builds a city, finding the gate they may enter; if a person attains rebirth in [the Land of] Peace and Bliss, this is the accomplishment of the gate of the Mahāyāna. Why did the Buddha originally arouse this vow? He saw that in some lands, although there are the assemblies of the Buddha, Tathāgatas, sages, and worthies, because of the land's turbidities, the one is divided to preach three; or a knitted brow incurs reproach, or a pointed word invites blame. Therefore he made the vow: "May my land be entirely of the single flavour of the Mahāyāna, of the single flavour of equality, where ruined roots and seeds are ultimately never born, and even the names of women and the disabled are severed." Therefore it is said: "In the realm of the Mahāyāna roots of good, / all are equal, without names of blame or reproach; / women and those with defective sense-faculties, / and the seeds of the two vehicles are not born."
