三、淨背捨身作證者，如《摩訶衍》中說：「緣淨故淨，遍身受樂，故名身作證。」所以者何？行者欲入是三背捨，於二背捨後，心即不受，觀外不淨，悉皆壞盡散滅，無有遺餘，亦不受大喜勇動，但攝心諦觀八色光耀之相。取是相已，入深三昧，鍊此八色，極令明淨，住心緣中，即泯然入定。定發之時，與樂俱生，見外八色光明清淨皎潔，猶如妙寶光色，各隨其想，昱晃明照，遍滿諸方，外徹清淨，外色照心，心即明淨，樂漸增長，遍滿身中，舉體怡悅。既證此法，背捨根本，心不樂著。是則略說證淨背捨相，亦名無漏三禪。是中具足五支，深思可見，乃至四禪淨色亦復如是，皆淨背捨所攝，但以無遍身樂為異耳。

Third is the liberation of the pure realized by the body. As said in the Mahāyāna [treatise]: 'Because the object is pure, it is pure; experiencing bliss throughout the entire body, it is called realized by the body.' Why is this? When the practitioner wishes to enter this third liberation, after the second liberation their mind does not accept [its states]; contemplating external impurities, all are completely destroyed and dispersed without remainder; nor do they accept the agitation of great joy. They merely gather the mind and closely contemplate the marks of the eight-colored radiance. Having taken these marks, they enter deep samādhi, refining these eight colors to make them exceedingly clear and pure. Settling the mind on the object, they tranquilly enter absorption. When the absorption arises, it is born together with bliss; they see the external eight-colored light as clear, pure, and spotless, like the light and color of wondrous jewels, each shining brightly and illuminating according to its mental image, filling all directions with thorough purity outside. As the external forms illuminate the mind, the mind becomes clear and pure; bliss gradually increases, filling the whole body, and the entire physical frame is filled with joy. Having realized this dharma, they turn away from and abandon the fundamental [dhyāna], their mind taking no delight or attachment in it. This is a brief explanation of the marks of realizing the pure liberation, also called the undefiled third dhyāna. Within it the five factors are complete, which can be seen upon deep reflection. This applies all the way to the pure forms of the fourth dhyāna as well; all are subsumed under the pure liberation, differing only in lacking bliss throughout the entire body.
