新譯華嚴經七處九會頌釋章 1.21

1.21

定其說處門者，問曰：說此經處為是淨土？為是染土？若是淨土，何故經云摩竭提國等？若是染土，何故經云此蓮華藏世界海等？答曰：說此經處，染淨二土鎔融相攝，有其四門：一、本從末門，唯娑婆說。二、末從本門，唯華藏說。三、本末雙顯門，如經云華藏界中娑婆界等。四、本末雙絕門，以就果海不可說故。此上四門合為一土，鎔融無礙，隨說皆得。

As for the gate of determining the places of preaching: Question: Is the place where this sūtra was preached a pure land, or is it an impure land? If it is a pure land, why does the sūtra mention the country of Magadha and so forth? If it is an impure land, why does the sūtra mention this Lotus Treasury Ocean of Worlds and so forth? Answer: As for the place where this sūtra was preached, the two lands—impure and pure—are fused and mutually contain each other; there are four gates: 1. The gate where the root accords with the branches: it is preached solely in the Sahā world. 2. The gate where the branches accord with the root: it is preached solely in the Lotus Treasury [world]. 3. The gate where both root and branches are simultaneously manifested: as when the sūtra says, "within the Lotus Treasury realm there is the Sahā realm," and so on. 4. The gate where both root and branches are mutually transcended: because, approaching the ocean of fruition, it cannot be spoken. The above four gates combine into one land, fused without impediment, valid however it is stated.
