大毘盧遮那經阿闍梨真實智品中阿闍梨住阿字觀門 1.14

1.14

Therefore the sūtra states: 'The beginning, middle, and end aspects of *ka*, *ca*, *ṭa*, *ta*, and *pa*, added with the categories of equanimity (*samādhi*), naturally enter one another, spontaneously attaining the practice of bodhicitta, accomplishing equal and perfect awakening, and parinirvāṇa.' This refers to the meaning of the initial four tiers of *A*, *Ā*, *Aṃ*, and *Aḥ*; furthermore, the twenty syllables such as *ka*, *ca*, *ṭa*, *ta*, and *pa* are the meaning of the middle; the twelve syllables from *I*, *Ī* to *O*, *AU* are the meaning of the added categories of equanimity; and the twenty syllables such as *ṅa*, *ña*, *ṇa*, *na*, *ma* up to *jha*, *ja*, *ña*, *dha*, *bha* are the meaning of the final aspect.
