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

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.
