"Huayan" is an unmoving and silent field that pervades the Dharma Realm. Therefore, it is said that there is no difference in body and appearance, and it is infinite and infinite. This is just like what the Big Book says: Amitabha Buddha is always in the west and is also present in the ten directions. ——"Buddha Speaks of Amitabha Sutra"
"Not moving" means that the Sambhogakaya of Lusena Buddha is not moving under the bodhi tree, or in the Huazang World, or in the Paradise World. The incarnation can go to many places.
There is a correspondence here, which may be a bit far-fetched, but it seems that we can make a correspondence between this "field of immovable silence, pervading the Dharma Realm" and "the gate of subtle compatibility and establishment".
"Subtle Compatibility Anlimen" means that any subtle dharma can tolerate all dharma. Because its dependent origin nature is unobstructed and free, it can be compatible with both large and small and can stand independently.
"The Avatamsaka Sutra" says that the Sambhogakaya of Lusena Buddha sits motionless on the Great Lotus Platform. One flower, one Tathagata, and the flower leaves can appear hundreds of thousands of billions. The incarnation of Sakyamuni Buddha; Sakyamuni Buddha sat under the Bodhi tree in Jambudvipa for many days and four days, enlightened and became a Buddha, teaching and transforming all living beings.
After Sakyamuni Buddha attained enlightenment and became a Buddha under the Bodhi tree, he preached the Avatamsaka Sutra for three to seven days. People like us in this world see him as silent and motionless, but we don't know that he goes to seven places and nine meetings, and at the same time he goes to the Trayast, Tusita, and Brahma heavens to preach sutras and sermons.
The same is true for Amitabha. We often recite, "In the light of the Buddha, there are countless millions of transformed Buddhas, and the number of transformed Bodhisattvas is also boundless." It means that Amitabha Buddha's Sambhogakaya is sitting in the lotus in the Land of Ultimate Bliss. The lotus shines, and countless transformed Buddhas appear in the light. The transformed Buddha is also There are countless Bodhisattvas as retinues and attendants.
These Buddhas and Bodhisattvas are immobile in the Land of Ultimate Bliss, but their incarnations are in the innumerable worlds in the four dimensions of southeast, north, and west, to establish countless sentient beings on the supreme and true path. For example, Master Shandao, Master Yongming, Master Chu Shi, and Zen Master Fengqian all have records that they are the incarnations of Amitabha.
The Sambhogakaya of Buddha and Bodhisattva remains immobile in the Land of Ultimate Bliss, and incarnates throughout other worlds, guiding sentient beings with predestined relationships to the righteous path of Buddha. This is the same as what is said in the Avatamsaka Sutra.
