大毘盧遮那經阿闍梨真實智品中阿闍梨住阿字觀門 1.20

1.20

阿闍梨若能如是了達不動之輪而布諸字，其體自然身有所表無非密印；口有所說皆是真言；意常止住無非觀門。凡有見聞觸知之者，皆必定於無上菩提，所成福利真實不虛。若能如是即同毘盧遮那如來，而作佛事常照世間。

If the ācārya can thus fully comprehend the immovable wheel and arrange the letters, his physical form naturally becomes such that whatever bodily gesture he displays is none other than a secret seal; whatever he speaks with his mouth is all mantra; and whatever is continuously maintained in his mind is none other than the contemplation gate. Whoever sees, hears, touches, or knows him is invariably destined for unexcelled awakening, and the blessings and benefits accomplished thereby are real and not vain. If he can do so, he is identical to Vairocana Tathāgata, performing the Buddha's deeds and constantly illuminating the world.
