首楞嚴義疏注經 4.571

4.571

菩提，云知覺，即智果。涅槃，云寂滅，即斷果。離偽妄無遷改，故曰真如。照察不變，名為佛性。菴摩羅，云無垢，離障所顯，即白淨無垢識也。不與妄染相應，含藏無量功德，名空如來藏。能現身土，離倒圓成，鑒周萬有，名大圓鏡智。七名雖別，一體無殊，堅固凝然，常住不動如金剛也。

Bodhi is translated as awareness, which is the fruition of wisdom. Nirvāṇa is translated as quiescent cessation, which is the fruition of abandonment. Free from falsity and without change, it is called tathatā. Illuminating, examining, and unchanging, it is called buddha-nature. Amala is translated as immaculate; revealed through freedom from obstructions, it is the pure, immaculate consciousness. Not corresponding with false defilements and containing immeasurable merit, it is named the empty tathāgatagarbha. Able to manifest bodies and lands, free from inversion, consummated, and discerning all existences, it is called the great perfect mirror wisdom. Although the seven names differ, the single essence is not distinct, being solid, congealed, permanently abiding, and immovable like a vajra.
