首楞嚴義疏注經 8.121

8.121

「行與佛同，受佛氣分，如中陰身自求父母，陰信冥通，入如來種，名生貴住。」

"When his practice is identical with that of the buddhas, receiving the Buddha's vital energy—just as an intermediate-state body seeks its own parents, tacitly communing with the intermediate consciousness and entering the lineage of the Tathāgata—this is called the Abode of Noble Birth."
