大毘盧遮那經阿闍梨真實智品中阿闍梨住阿字觀門 1.9

1.9

夫阿闍梨若觀此字而相應者，即是自身同於毘盧遮那佛身，亦名金剛不壞之身、亦名普現色身、亦名三種意生身。

When an *ācārya* contemplates this syllable and achieves correspondence, their own body becomes identical to the body of Vairocana Buddha; it is also named the adamantine indestructible body, the universally manifesting physical body, and the three kinds of mind-made bodies.
