大毘盧遮那成佛神變加持經蓮華胎藏菩提幢標幟普通真言藏廣大成就瑜伽 2.28

2.28

“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.”
