2.28

「祕密主！如是字門，如來神力之所加持。我今普觀諸佛剎土，無不見此遍一切處法門彼諸如來無有不宣說者。真言門修菩薩行者，於此法門應勤修學，於舸遮吒多波初中後相加，以等持品類相入，自然獲得菩提心行成等正覺，如大日世尊而轉法輪。」

“Lord of Secrets! Such syllable-doors are consecrated by the supernatural power of the Tathāgata. As I now look universally upon the buddha-lands, there is none where I do not see this all-pervading Dharma-door, and none of those Tathāgatas fails to expound it. Practitioners cultivating bodhisattva practices in the mantra door should diligently cultivate and study this Dharma-door, adding to one another the initial, middle, and final [syllables] of ka, ca, ṭa, ta, and pa; through the mutual penetration of samādhi categories, they naturally attain bodhicitta practices and realize equal and perfect enlightenment, turning the wheel of the Dharma like the World-Honoured One Mahāvairocana.”
