第十五馬藏相，有三種：初隱密相用中，照法界者，證理深也。照虛空界者，照事廣也。寶嚴法界者，行嚴真性出生妙果也。二一相現一切相海用中，釋顯此名，復照現餘一切佛神力。三法界海相中，體能照現十方諸佛及法輪海，用能示現自塵數相。此上是十身相。若化身相者，《智論》馬陰藏相，佛令弟子見陰藏相者，為決疑故。又有言化作馬寶象寶示諸弟子，我陰藏相亦如是。

Fifteenth, the marks of the horse-sheath [organ] are of three kinds: In the first, the function of the hidden mark, "illuminating the dharmadhātu" is realizing principle deeply; "illuminating the empty space" is illuminating phenomena broadly; "jewel-adorning the dharmadhātu" is practice adorning true nature to bring forth wondrous fruition. Second, in the function of one mark manifesting an ocean of all marks, it explains and reveals this name, and further illuminates and manifests the supernatural powers of all other Buddhas. Third, in the mark of the ocean of the dharmadhātu, its essence can illuminate and manifest the Buddhas of the ten directions and the ocean of the dharmacakra; its function can display its own dust-numbered marks. The above are marks of the ten bodies. If they were the marks of the nirmāṇakāya, according to the Dà zhìdù lùn on the mark of the horse-sheath concealed organ, the Buddha caused his disciples to see the mark of the concealed organ in order to resolve doubts. There is also the saying that he magically manifested a horse-jewel and elephant-jewel to show his disciples, [saying,] "The mark of my concealed organ is also like this."
